Mirrorless cameras are the trailblazers of the camera world. Unlike DSLRs, which have optical viewfinders and internal mirrors, they’re pioneering a completely electronic form of a composition that is evolving quickly and bringing lots of exciting new features.
These include everything from electronic viewfinders (or EVFs) to autofocus systems that cover the entire frame, rather than just a diamond in the centre. But with mirrorless cameras coming in all shapes and sizes, it can be difficult to choose which one’s right for you. Luckily, we’ve rounded up the best ones for every type of photographer.

best overall mirrorless camera
The Sony A7R III is our pick of the best overall mirrorless camera because it combines a high resolution 42.4MP sensor with seriously high speed 10fps continuous shooting. The A7R III is as versatile as a professional mirrorless camera can get.
If you want a small, well-built entrée to mirrorless photography, the Olympus OM-D E-M10 Mark III is great value and ideal for beginners. For those who prefer to avoid editing and just want to shoot high quality JPEGs, Fujifilm’s X-T20 is an excellent choice. And if you’re really serious about your snapping and want the best mirrorless camera around, then it’s hard to look past the Sony A7 III.
After months (nay, years) of rumours, both Canon and Nikon have announced their first full-frame mirrorless cameras in the summer of 2018. Nikon was first with not one, but two, models, the Nikon Z7 and the Nikon Z6. Not long after, Canon followed with the Canon EOS R.
If you’re in the market for a different style of camera head to one of these more specific round-ups:

How we test mirrorless cameras
We put every mirrorless camera we test through a series of rigorous tests to analyse how each model performs. All results are analysed by the very best industry software. This makes our reviews the most authoritative of any you’ll read.
We test for colour – different sensor and camera image processors can interpret colour differently, while this can also shift at different ISO sensitivities. We then get down to the nitty-gritty of resolution, with our lab tests showing us exactly how much detail each camera’s sensor can resolve. Even though cameras can share identical pixel counts, some perform better than others. Then we look at image noise, since different cameras can produce cleaner images at higher ISOs than others.
Finally, we get out and shoot with every camera in real-world conditions, just as you will, to find out how they perform in day-to-day use.

Best entry-level mirrorless camera: Panasonic Lumix GX800
- Small and easy to use
- Capable of 4K Video and 4K Photo
- Cheapest Panasonic CSC around
- No eye viewfinder
Panasonic offers a generous range of mirrorless models to suit all price points and levels of ability. Released at the start of 2017, the Lumix GX800 is Panasonic’s current entry-level mirrorless model and, as such, is primarily aimed at casual users looking for an easy-to-use interchangeable-lens camera that’s capable of discernibly better image quality than a smartphone or budget compact.
The GX800 is built around the same 16MP Live MOS sensor as the more advanced GX80, which results in a similarly high standard of image quality overall. The GX800’s optical low-pass filter has also been removed for enhanced fine detail. Image processing is taken care of via Panasonic’s proprietary Venus Engine, which facilitates a native sensitivity range of ISO 200-25,600 (plus an extended lower setting of ISO 100) and a top continuous shooting speed of 5fps.
In addition the GX800 is also capable of recording 4K video at up to 30fps, and comes with Panasonic’s innovative 4K Photo mode, which enables 8MP still images to be extracted from 4K video footage in a variety of ways to ensure that you never miss a moment.
In terms of size and weight the GX800 is the smallest and lightest mirrorless camera in the current Lumix range. On top of this, it also benefits from some retro rangefinder styling, giving it an undoubtedly stylish appearance. While buttons are a little scarce and the camera lacks an electronic viewfinder – or indeed any means to attach one – the rear display flips up by 180 degrees so that it can be made to face the same direction as the lens for easy selfies. Better still, the rear display doubles up as a touchscreen, providing intuitive control over the camera.
Best entry-level mirrorless camera with a viewfinder: Olympus OM-D E-M10 Mark III
- Compact, retro body
- Excellent JPEG image quality
- Superb in-body image stabilisation works with every lens
- Fast, accurate autofocus with static subjects
- Over-simplified in-camera raw conversion
- Less reliable autofocus with moving subjects
If you’re looking to upgrade from a smartphone to your first proper camera, there is now a huge range of mirrorless options with built-in viewfinders. While Fujifilm’s X-T100 is arguably the most desirable, the Olympus OM-D E-M10 Mark III remains our pick due to its all-round talents and huge choice of lenses.
The OM-D E-M10 Mark III has a 16-megapixel Micro Four Thirds sensor, which is smaller than the APS-C sensors found in the likes of Fujifilm’s X-T100. Built-in image stabilisation helps to compensate for this, though, and the smaller sensor size means you do get much faster burst shooting at 8.6fps too.
The sensor is paired with Olympus’ latest TruePic VIII image processor – the same one used in the flagship OM-D E-M1 Mark II – which helps to boosts its performance in low light. An even bigger benefit is the ability to record 4K video at up to 30fps, along with 120fps slow-motion video at 720p HD. Sadly, there’s no way to attach an external microphone to the E-though, nor does it have a headphone output, so your vlogging options are a little limited.
Still, autofocus is very impressive, thanks to its 121-point contrast detect system. The AF points cover practically the entire frame and while focus acquisition isn’t quite as fast as some of the hybrid AF systems employed by other mirrorless manufacturers, it’s still impressively quick. Olympus’ in-camera 5-axis image stabilisation technology is also on hand to provide up to four stops of shutter speed compensation – even with non-stabilised lenses attached.
Though it lacks the weather sealing of models higher up the Olympus range it still feels solid and sits in the hand nicely thanks to its redesigned handgrip and sculpted thumb rest.
This all adds up to a fantastic little camera for anyone who’s upgrading from a smartphone or looking for a take-anywhere second camera. The OM-D E-M10 Mark III combines a strong feature set, classic design and a huge choice of lenses, making it our pick at this price point.
Best mirrorless camera for vlogging: Canon EOS M50
- Compact size and light weight make it easy to carry everywhere
- Excellent image quality, with reliable metering and auto white balance
- Quick and accurate autofocus, even with adapted EF-mount DSLR lenses
- Easy-to-use interface that still gives extensive control over settings
- Single-dial control slower to use than twin-dial competitors
- Overly contrasty viewfinder blocks up shadow details
- Poorly implemented manual focus magnification
- Very small range of native EF-M lenses
The Canon EOS M50 slots into the company’s lineup of mirrorless cameras between the EOS M100 and EOS M6. It offers a similar degree of external control to the firm’s beginner-friendly EOS 200D DSLR, but with an electronic viewfinder built-in, alongside a fully-articulated touchscreen.
It’s built around a new generation of Canon’s Dual Pixel CMOS AF sensor, which is now capable of phase-detection autofocus across a wider area of the frame. With 24.1MP resolution, it offers a sensitivity range of ISO 100-25,600 that’s expandable to ISO 51,200. Continuous shooting is a real strength of this camera: 10fps with focus fixed, or 7.4fps with focus adjusted between shots.
For the first time on an EOS model, the EOS M50 provides a silent shooting mode that uses a fully electronic shutter. You get Canon’s Auto Lighting Optimiser for balancing shadows and highlights in high contrast scenes and there’s a good selection of basic modes and subject-based scene modes for beginners to start with before they progress.
Most notably, the EOS M50 marks the debut of the firm’s latest DIGIC 8 processor, making it the first Canon consumer camera capable of recording 4K video.
As you’d expect, Wi-Fi, NFC and Bluetooth connectivity options are all available, with the latter capable of forming an always-on connection to your smartphone using the free Camera Connect app for Android or iOS. When sharing photos, you can either push your favourite shots from the camera to your phone while browsing in playback mode, or view your images on your phone and pull them across.
The EOS M50 is equipped with a 2.36-million dot, 0.39-type EVF with a magnification of around 0.62x. Beneath the EVF is a 3-inch 1.04m-dot LCD, with a fully articulated design. It can tilt upwards or downwards for waist-level or overhead shooting in either portrait or landscape format, face fully forwards for vlogging, or even fold away with the screen facing inwards to protect it from scratches.
Autofocus performance is as good as you could hope for: it’s silent and goes about its business accurately. The EOS M50 also works remarkably well with Canon EF-mount DSLR lenses using the Canon EF EOS M-mount adapter that can be picked up for around £109.
With the EOS M50, Canon has produced a very likeable camera that manages to be simple and approachable for beginners or vloggers, while also offering a full degree of manual control for enthusiasts. It has some stiff competition and the only major thing it has against it is the limited number of lenses that are currently available in the Canon EF-M lens range.
Best enthusiast mirrorless camera: Fujifilm X-T20
- Excellent image quality
- Advanced AF system
- Tactile controls
- Brilliant handling
- Poor battery life
Released at the start of 2017, the X-T20 succeeds 2015’s X-T10 model bringing with it a range of improvements that are, at least in part, borrowed from Fujifilm’s flagship X-T2 model. This includes Fujifilm’s latest X-Trans CMOS II sensor, which provides 24.3MP of effective resolution compared to the X-T10’s 16MP.
This is paired with Fujifilms’s X Processor Pro image processor to provide a native sensitivity range of ISO 200-12,800 that can be further expanded to the equivalent of ISO 100-51,200. While continuous shooting remains at a steady 8fps using the mechanical shutter, the X-T20 can also shoot at up to 14fps via its electronic shutter.
The X-T20’s hybrid autofocus system has also been improved and now employs a total of 91 AF points, compared to 49 on the X-T10. The new AF module includes 49 phase-detection AF points, located in the central portion of the viewfinder. The rear LCD also benefits from a higher resolution (1.04m-dots vs 922k-dots) and touchscreen control – a feature that the X-T10 lacks altogether. In addition, the X-T20 is also capable of recording 4K video whereas the X-T10 maxed out at 1080p Full HD capture.
The X-T20 retains the same 2.36m-dot electronic viewfinder as its predecessor, and this provides 100% coverage at a magnification of 0.62x. In terms of design, the X-T20 shares the same stylish retro rangefinder aesthetic of its predecessor, with milled aluminium dials on the top-plate and dual control wheels providing a pleasingly tactile user experience. While the predominantly magnesium-alloy construction looks great and adds undoubted durability to the camera overall, the X-T20 is not weather sealed like the more expensive X-T2.
Best APS-C mirrorless camera: Fujifilm X-T3
- Speedy autofocus
- Good range of video options
- Fantastic image quality
- Pleasant to use
- Lack of in-body image stabilisation
- Screen tilts, not articulates
- Average battery life
If you’re looking for an all-rounder mirrorless camera but don’t want to break the bank, the Fujifilm X-T3 is one of the best options you can go for.
A replacement for the X-T3, the X-T3 follows on from its predecessor with the same classic style that is likely to be adored by lovers of vintage cameras. All those tactile buttons and dials, many of which are customisable, make for a fantastic shooting experience, too.
Outwardly, not too much has changed between old and new, but on the inside, there’s been very welcome upgrades made to the sensor and processor, as well as a raft of intriguing new video capabilities that are sure to draw the attention of any budding movie maker.
Fuji’s X series uses an APS-C sized sensor. That means they’re not the smallest, but they’re also not the largest. Fujifilm uses this to its advantage by pointing out that this gives you the best balance between image quality and portability – after all it’s got a ‘super full frame’ range too in the shape of its medium-format GFX models, if you want the ultimate in picture quality.
With its superb autofocusing, fantastic image quality and great handling, you might consider the X-T3 to be somewhat of a mini X-H1, but without the in-body image stabilisation. Battery life is also a tiny bit disappointing, so you may want to shell out for an extra one if you’re intending to use the X-T3 on your travels.
Best high-end mirrorless camera: Olympus OM-D E-M1 II
- Long battery life
- Cinema 4K
- High resolution viewfinder
- Excellent tracking focus
- Very expensive
- Strange menu setup
- Only one UHS-II memory card slot
In recent years the digital camera industry has seen a move towards the use of ultra-fast image processors that can handle the increased data produced by high-resolution sensors and speedily process it, thereby enabling photographers to shoot extended bursts at high speed for longer than was previously possible. Of course, this is especially valuable to sports and action photographers but equally useful to wildlife shooters too. Released early in 2016, the flagship Olympus OM-D E-M1 II epitomises this new breed of camera in that it’s built from the ground up for speed and performance.
While the OM-D E-M1 II’s 20.4MP sensor represents a step up from the 16MP sensor of the original OM-D E-M1, it’s the TruPic VIII image processor that really makes the OM-D E-M1 II tick. This utilises two quad core processors, one of which is assigned to image processing duties while the other drives the OM-D E-M1 II’s autofocus system. This enables the OM-D E-M1 II to shoot continuously at 18fps via the mechanical shutter while maintaining active AF. If you want to shoot even faster, the E-M1’s electronic shutter can be employed to facilitate speeds of up to 60fps, albeit with focus locked on the first frame.
Autofocus is another area where the OM-D E-M1 II shines. Whereas the original OM-D EM-1 used a 37-point system, the OM-D E-M1 II gets a more advanced 121-point system that covers around 80% of the frame with on-sensor phase-detection AF points, all of which are of the cross-type variety. Used to track moving subjects, the AF system performs exceptionally well. Furthermore the OM-D also benefits from built-in 5-axis image stabilisation technology, which provides up to 6.5 stops of compensation.
Elsewhere the OM-D E-M1 II gets 4K video recording at up to 30fps along with twin SD card slots and built-in Wifi. In terms of construction, the OM-D E-M1 II benefits from durable magnesium alloy construction and is weather-sealed against dust and moisture. For those looking to shoot at speed, the OM-D E-M1 II is definitely one to put on the shortlist.
Best high-end mirrorless camera for action and sports: Panasonic Lumix G9
- Superb design and handling
- Excellent 4K & 6K photo modes
- Well supported by Micro Four Thirds lenses
- Offers high-resolution 40MP & 80MP modes
- Positioning of AF toggle could be better
- Lacks battery level indication as percentage
- Burst shot mode descriptions aren’t clear
- No in-camera panoramic mode
The Panasonic G9 sits beside Panasonic’s premium GH5 and GH5S models in the Lumix G lineup. Whereas the GH series has always set about appealing to videographers, the G9 is out to fulfil the demands of passionate stills-focused photographers. It does this with an impressive specification, however it’s the blistering speeds that it’s capable of that really sets it apart from many other cameras.
Shooting continuously in its AF-S mode, the G9 can rattle out a burst at 12fps for as many as 60 frames in RAW, or at 60fps for 50 frames in RAW by activating the camera’s electronic shutter. Switching the camera over to its continuous AF mode (AF-C) sees the burst speed drop, but to a highly respectable 9fps using the mechanical shutter or 20fps using the electronic shutter.
The G9’s new 5-axis Dual I.S II image stabiliser, which offers 6.5 stops of compensation to counteract camera shake when shooting stills or movies, also has a dual-purpose. It allows the camera to offer a new 80-megapixel high-resolution mode whereby the sensor is shifted precisely between eight shots to create a single image with much finer detail. It’s wonderfully executed and is so simply to use.
There’s so much more to like about the camera. It has a top-plate LCD like you get on most DSLRs, a superb 3680k-dot resolution electronic viewfinder with 0.83x magnification, and a sensitive 3-inch, 1040k-dot vari-angle touchscreen. It combines all of the above with a spritely autofocus system, relying once again on a formula of contrast detection and Depth From Defocus (DFD) technology.
It may lack a really high-end feel and an in-camera panoramic mode, but it’s an incredibly versatile mirrorless camera that’s very capable of delivering satisfying results in the hands of those who love photography. There’s great value to be had from buying the Panasonic Lumix G9 and it’s by far the company’s best stills camera to date.
Best pro mirrorless camera for video: Panasonic GH5S
- Superb video quality and flexibility
- Excellent in low light conditions
- Compact, tough and lightweight design
- Average stills performance
If you prize video quality above stills, then this is the best compact system camera you can buy. Impressively for a camera so small, the Panasonic Lumix GH5S can capture 4K footage at 60fps, with Hybrid Gamma Log HDR and no limits on the recording time.
Its comparatively average still photos, which lack detail due to its 10.28-megapixel sensor, mean the GH5S isn’t even really a mirrorless all-rounder. Instead, it’s a pro-quality video camera in an incredibly small, weatherproof package – and in this field, none of its rivals come close.
The 10-bit footage the GH5S produces is astonishingly sharp and natural-looking, even straight out of the camera without any colour grading. Thanks to its ultra-sensitive sensor’s large pixels, low light performance is impressive too, with an ISO range that stretches to 51,200 in normal mode and 204,800 in extended mode.
With some handy slo-mo options in 4K and 1080p (with the latter available at 240fps) and the ability to record HDR footage, the video options are superb for a camera of this size and price.
If you do like to shoot still photos as well, there are unquestionably more well-rounded options at this level, such as Olympus’ OM-D E-M1 II and Sony’s A7 III. But if it’s pro-quality video from a DSLR-style body that you’re after, the Panasonic GH5S is the best mirrorless camera for videographers that we’ve seen so far.
Best overall full-frame mirrorless camera: Sony A7 III
- Excellent value for money
- Improved battery stamina
- Fast and responsive autofocus system
- Revised button layout for intuitive control
- AF point illumination could be improved
- Convoluted menu system
- Thin plastic port covers aren’t weather-sealed
- Handles poorly with large gloves in cold climates
The Sony A7 III is a sensational mirrorless camera that improves on the Sony A7 II and introduces many of the niceties of the A7R III and A9, at a price that falls below £2000 from launch. Sony calls the A7 III its most basic full-frame camera in the Alpha 7 series, but it’s far from lacking when you take a closer look at what features it offers for the money.
It’s equipped with a 24.2-megapixel full-frame sensor, which benefits from backside-illuminated architecture. You get a wide ISO range that can be expanded to ISO 50-204,800, fast continuous burst shooting up to 10fps with autofocus and exposure adjustment, and a fully electronic shutter, making it possible to shoot silently when you want to avoid disturbing a subject.
The headline feature of the A7 II was its 5-axis in-body stabilisation. This advanced IS system carries over to the A7 III, but now offers up to 5 stops of stabilisation compared to 4.5 stops on its predecessor. Another improvement sees the A7 III use the same uprated NP-FZ100 battery as the A7R III and A9, offering over twice the capacity of the old NP-FW50. It also gains twin SD card slots, but only one supports the UHS-II type.
In terms of autofocus, the A7 II’s AF system has been replaced by a complex arrangement of 693 phase-detection points and 425 contrast-detection points. These cover 93% of the frame. Autofocus is further improved by employing the same AF advancements as used in the Sony A9. The difference in the speed and accuracy of the A7 III’s focusing is noticeable coming from the older A7 II.
With a good level of customisation and a revised button layout that makes operation more intuitive, the A7 III is an extremely enjoyable camera to use. It inherits the AF joystick from the A7R III and presents a new exposure lock (AEL) button below the exposure-compensation dial, a new AF-ON button, and an improved rear scroll dial that’s far less fiddly.
Other improvements on the A7 III are found at the rear, where a 2.3m-dot EVF with 0.78x magnification and 3in 922k-dot LCD touchscreen take pride of place. The EVF has a lower resolution than the A7R III, but is complete with Zeiss T* coatings to reduce obtrusive reflections.
The A7 III has come on a long way from the original A7 and A7 II. It does exactly what serious photographers want in a body that’s smaller and lighter than rival DSLRs. It’s quick, it’s highly versatile and delivers excellent image quality when more is asked from the sensor in low light.
Sony has made a superb all-rounder with the A7 III. By pricing it under £2000 (body only), it’ll appeal to a huge number of photographers who are looking to advance to full-frame, as well as those considering the switch from DSLR to mirrorless.
It seems likely that Canon and Nikon will release direct rivals to the A7 III in 2018, but Sony has stolen a mirrorless march on them both – the A7 series continues to get more appealing, and right now the A7 III is our favourite all-round mirrorless camera.
Best high-resolution full-frame mirrorless camera: Nikon Z7
- Compact, lightweight design with well-placed controls
- Superb electronic viewfinder
- In-body image stabilisation gives sharper images with any lens
- AF area is invisible when moved using the joystick
- Rear screen only tilts up or down
- Handgrip too close to the lens for shooting with gloves
The odds were against Nikon coming right out of the gate with a first-generation, full-frame mirrorless classic, but that’s exactly what it’s done with the Nikon Z7.
A 45.7-megapixel with a 493-point AF system, it’s fair to say the Z7 isn’t for beginners – this is a high-resolution camera for professionals who demand maximum detail and like to print large. It’s also the first serious mirrorless rival to Sony’s A7R III.
Choosing between these two cameras will very much depend on which lenses you already own, but we think the Z7 shades it thanks to its superior handling and touchscreen controls. With its deep grip and chunky build, it feels like a slimmed down Nikon D850 – and brings the benefits of a fantastic, 3.6-million dot electronic viewfinder and in-body image stabilisation.
Its superb sensor produces extremely detailed photos with great colours, even at high ISOs. The Z7’s only slight weakness is that the autofocus struggles ever so slightly with erratic, fast-moving subjects compared to rivals like the Sony A9. But its AF is otherwise fast and accurate and images are virtually noise-free even at ISO 1600.
Sony’s subject tracking and AF speeds may be superior, but the Nikon Z7 is a more enjoyable camera to use. And unless the single card slot is a deal-breaker, it’s the best high-res mirrorless camera you can buy today.
Best pro mirrorless camera: Sony A9
- Excellent handling and controls
- Superb autofocus tracking
- High-speed shooting with minimal distortion
- Excellent electronic viewfinder with zero blackout
- Impressive battery life
- AF area not highlighted in viewfinder when moved via the joystick
- Touchscreen woefully under-used
Released in the spring of 2017 the Sony A9 is a high-speed full-frame mirrorless camera that’s designed to compete directly with Nikon and Canon’s professional-grade DSLRs. More specifically, it’s high burst speed and remarkable autofocus tracking abilities mark it out as an ideal camera for high-speed sports and action photography, while it’s extended sensitivity settings and silent shooting abilities also increase its appeal to professional weddings and events shooters.
Making all this possible is a new 24MP full-frame Exmor RS sensor that employs Sony’s stacked design whereby the sensor circuitry is positioned directly below the photodiodes along with an integral DRAM chip that feeds the data to the A9’s powerful BIONZ X image processor up to 20 times faster than a conventional chip. In real-world use this enables the A9 to shoot continuously at up to 20fps via its electronic shutter with AF-C enabled, with no rolling shutter distortion effects and a top shutter speed of 1/32,000sec. Switching to the mechanical shutter, maximum burst speed drops to 5fps with a maximum shutter speed of 1/8000sec.
The other big highlight of the A9 is its AF system, which employs 693 phase-detection points that cover approximately 93% of the frame. With its ability to refocus up to 60 times a second, the A9’s tracking abilities with moving subjects are also exceptional. Five-axis image stabilisation in the guise of Sony SteadyShot is also present, helping to keep images sharp even at slower shutter speeds.
Build quality is, as you’d expect of a £4.5k flagship camera, very good indeed with the A9 wrapped in durable magnesium alloy and fully sealed against dust and moisture. Physical controls are plentiful too, and in addition to twin control dials there’s also a dedicated joystick for speedy AF point placement. The 3.68m-dot EVF, meanwhile, is one of the sharpest on the market, while the 3-inch rear LCD doubles up as a touchscreen. 4K video capture at 25fps is supported, however the A9 does not offer any “flat” profiles for grading purposes.
Best mid-range full-frame mirrorless camera: Canon EOS R
- Great image quality
- Superb EVF
- Customisable handling
- No in-body stabilisation
- Quite bulky
We waited what felt like a lifetime for Canon to finally pull its finger out and bring us a full-frame mirrorless camera. Perhaps after all that waiting, the Canon EOS R is a bit of an anti-climax, but never-the-less it’s an excellent first entry for an entirely new range of cameras.
It looks and feels a lot like a traditional Canon DSLR, but of course, being mirrorless, it’s just that little bit smaller and lighter so as to make it a more comfortable overall shooting experience. If you’re already a Canon shooter and don’t watch to ditch all your lenses to go elsewhere, it’s the obvious choice for making the leap into the mirrorless world (though you will need an adapter to use your lenses).
There’s a lot to like about the Canon EOS R, and above all else, the images that it is capable of producing are superb. There’s also pretty good handling, with nifty features like the customisable touch-sensitive slider just next to the viewfinder.
Sadly, there’s also plenty to dislike – with the lack of in-body image stabilisation being a pretty big one. Although it might be smaller than a DSLR, it’s still bulkier than other mirrorless full-frame models on the market, so you may also not consider it enough of a size and weight saving to merit forking out for.
Cropped 4K video shooting is another downside, but for the average photographer, that’s going to be less of an issue – but for videographers used to shooting with Canon’s superb 5D series, it’s a bit of a let-down.
Still, if you’re a keen Canon user and want o open yourself up to the benefits that mirrorless brings, this is the one to go for now – we’ll see what next year brings.
Best medium format mirrorless camera: Fujifilm GFX 50S
- Phenomenal resolution and dynamic range
- Intuitive controls
- More compact than you’d expect from medium format
- Removable viewfinder with optional tilt adapter
- Autofocus performance
- Touchscreen could be implemented further
- Out of its comfort zone when shooting action and sport
If you’re a pro photographer or commercial shooter, then Fujifilm’s new Medium Format mirrorless system is a highly tempting new option that produces some of the finest image quality you can currently buy.
The Fujifilm GFX 50S‘ 51.4-megapixel sensor is four times the size of the ones found in Fujifilm’s APS-C X- Series cameras, like the X-T20. Despite this huge sensor, the GFX 50S keeps the size down and the usability high by incorporating some of the many mirrorless design features that make the X Series such a compelling range of cameras.
Build quality is incredibly good, with the durable magnesium-alloy body able to withstand pretty much any environment outside the Arctic. As you’d hope for the price, Fujifilm has added some high-end, modern touches too, including a tilting, 3.2-inch touchscreen and a 3.69-million dot electronic viewfinder, which is also removable if you need to shed some bulk.
It might not be built for speed, which continuous shooting topping out at 3fps, but the GFX 50S’ image quality more than compensates. The level of detail is can resolve is astonishing and the dynamic range is so good you can pull back detail from places you didn’t think possible.
Combine this image quality with the X Series’ usability and you have a very compelling new medium format option. Of course, for most of us the GFX 50S price tag will be well out of reach, which means it’s well worth looking into hiring one out at £90 a day for a trip to the countryside. But in Medium Format terms it’s not overly expensive considering the Pentax 645Z costs £400 more and the Hasselblad X1D-50c is £1600 dearer.
As more G-Mount lenses arrive, this system is only going to get more compelling for pros and landscape photographers alike.
Incoming: new cameras to be reviewed soon
There’s never been a better time to be looking for a mirrorless camera, with a huge wealth of choice currently (or about to be) on the market. Here’s some upcoming models that could be finding they have a spot on our best mirrorless guide.
Nikon announced not just one, but two mirrorless cameras in the Z series. The Nikon Z6 is the more consumer-friendly version, with a lower resolution sensor and a cheaper asking price. It’s the that we expect will actually sell in the highest numbers, especially for those who don’t need such a high resolution. Otherwise, the body and handling, including features such as the electronic viewfinder, are identical across both bodies. Again, so far we’ve only had a brief hands-on with the Z6, but will be updating this as soon as possible.
Within just a few short weeks, the full-frame mirrorless market went from having one player, to four. The Panasonic S1 and S1R models were announced at Photokina 2018, part of a newly formed ‘L Mount Alliance’ between Leica, Sigma and Panasonic. These new full-frame mirrorless models will feature 47 megapixel and 24 megapixel sensors, and look set to shake up the market, perhaps even more so than the traditional manufacturers like Canon and Nikon. We’ll have to wait until next year to find out exactly how they perform though, giving the other rivals a bit of a jump.
Fujifilm GFX 50R
If full-frame just isn’t enough sensor for you, you could always go even further with medium format – which Fujifilm likes to call ‘super full frame’. The second model in the company’s esteemed GFX range, the Fujifilm GFX 50R pairs that huge medium-format sensor with a flatter, rangefinder style design.That should make it more appealing to documentary or possibly even street photographers, anybody keen to have the ultimate image quality and doesn’t mind a little bit of extra heft to get it.
Those are our top picks of the best mirrorless cameras. If you want to know more about what to look out for when buying a mirrorless camera then read on.
Mirrorless camera buying guide
The primary difference between a mirrorless camera and a traditional DSLR is that the latter is fitted with an internal mirror that bounces the image acquired through the lens up towards a phase-detection autofocus (AF) module in the ceiling of the camera before exiting through the optical viewfinder. Once focus is acquired and the shutter button is pressed this mirror raises up, exposing the sensor and capturing the image. In a mirrorless camera, though, there is no internal mirror, so light passes straight through the camera and directly onto the sensor.

When mirrorless models first came out this lack of a phase detection meant they had to use contrast-detect technology to acquire focus, which is slower than phase-detect AF. However, these days many mirrorless cameras use on-sensor phase-detection AF, often in combination with contrast-detect AF to produce AF speeds that rival those of DSLRs. In addition, the fact that there’s no mechanical mirror means mirrorless cameras are generally capable of much higher continuous shooting speeds. Some of the fastest mirrorless cameras can now rattle out a burst at up to 60fps after activating the electronic shutter.
Best mirrorless camera buying guide – EVF and sensor
One further issue with early mirrorless cameras was that the lack of an optical viewfinder meant an electronic one was required in its place. Early EVFs were clunky at best, offering a small and pixelated view. But these days, that’s simply not the case and the difference in quality between the high-resolution EVFs that many mirrorless cameras are now equipped with and their optical counterparts on a DSLR are far less pronounced.
If you’re going to be shooting high-speed sport and action, the other thing you’ll look out for is an EVF that features no viewfinder blackout. Viewfinder blackout refers to the period of blackout between each frame captured – something that can make it harder to keep up and track a subject successfully through the frame. The Sony Alpha 9 is currently one of the best mirrorless examples on the market with no EVF blackout.

While the very first mirrorless cameras were fitted with smaller Micro Four Thirds sensors jointly developed by Panasonic and Olympus, these days they’re equipped with a wide range of sensor sizes including APS-C and full-frame. Which of these is right for you will of course depend on your individual requirements and budget.
Below you’ll find a jargon buster that reveals some of the complex terminology associated with mirrorless cameras and our compilation of the finest examples to give you a better idea of which are best to buy.
Hybrid AF Systems: There are an increasing number of mirrorless cameras using innovative hybrid AF systems that combine on-sensor phase-detection with traditional contrast-detect AF. And with the new breed of ultra-fast processors dedicated to autofocus duties some mirrorless cameras are now able to outperform DSLRs in terms of AF speed.
Rear display: An increasing number of mirrorless cameras are now adding touchscreen functionality to the rear display, which makes operating the camera much speedier and more intuitive. How the screen is attached to the camera body is another important consideration – some are fixed, some can be tilted, while others use the infinitely more flexible vari-angle design.
Video: More and more new mirrorless cameras are adding 4K video capture. For those serious about video, the Panasonic Lumix GH5 is currently the only mirrorless model to offer broadcast quality 10-bit 10:2:2 4K capture. Be sure to check whether your desired model sports a dedicated microphone and/or headphone input as this does vary between models.
Media slot: All mirrorless cameras come with at least one SD memory card slot, although an increasing number of high-end models sport two. These can usually be configured to record data in a number of ways including using the second slot as an overflow or for raw images, or using one card for stills and the other for video. Support for the even faster UHS-II cards is currently limited to more advanced models.
Design: Broadly speaking, mirrorless cameras tend to fall into one of two camps in terms of their general styling: there are those that take classic rangefinder cameras as their inspiration, while others are designed to mimic the appearance and handling of a DSLR. Which is best for you is all down to personal preference. Just be sure to take build quality into account, as cheaper examples are unlikely to benefit from a tough magnesium alloy chassis and weather-sealed construction.
