Best mirrorless camera: Great cameras for every budget

Trusted Reviews whittles down its authoritative series of reviews to list the best mirrorless cameras currently on the market

Looking for a new mirrorless camera? We’ve rounded up all the best mirrorless cameras we’ve reviewed, along with the pros and cons of each, to create the ultimate guide. 

Mirrorless cameras have grown massively in popularity in recent years, offering a more portable and video-capable option than many similarly-priced DSLRs. Whether you’re in the market for your first mirrorless camera or looking to update your kit with a new one, you can find a breakdown of some of our favourite options below. 

There are a number of areas to consider when shopping for a new camera, including the image sensor, viewfinder, screen and features like autofocus and frame rate. It’s also important to look at the video capabilities, lens options and the camera’s battery life to get a good idea of which camera is best for you. 

We test all of these areas in our reviews and take the cameras out into the real world to see how they perform in a variety of circumstances. We also consider how user-friendly the software and controls are, as well as other important factors like pricing and availability.

If you haven’t yet decided on a specific type of camera, its worth checking out our other best lists to get a wider view of what’s out there and worth your cash. These include our guides to the best DSLRs, the best compact cameras, the best vlogging cameras, the best action cameras and the best instant cameras.

Nikon Z9

The best all-rounder on the list
rating-star rating-star rating-star rating-star rating-star


  • Robust and versatile design
  • 120fps shooting
  • 8K video recording


  • Expensive
  • Large and heavy body
  • Additional cost of CFexpress or XQD card

The Nikon Z9 is a fantastically versatile camera designed to serve professionals in a wide range of applications from wildlife to sports to fashion photography and video. 

At 1340g the large and square camera certainly isn’t lightweight, but it’s still significantly smaller and less heavy than Nikon’s flagship DSLR, the D6. The Z9’s body is weather-sealed and there are also grips and shutter release buttons on two sides to make snapping portraits as comfortable as landscapes. 

The 3000-nit electronic viewfinder has a 120fps refresh rate and there’s a sharp 4-axis monitor with a 170-degree viewing angle. 

The Z9 packs a 45.7-megapixel full-frame stacked CMOS sensor for rich and detailed images, as well as a 493-point autofocus system with 10 AF-area modes to choose from and detection for nine different subject types. There’s also an incredibly fast burst mode capable of capturing 11-megapixel JPEGs at up to 120fps with full AF/AE. 

Finally, there’s support for 8K video at up to 60p or 4K at up to 120p. 

Aside from the camera’s size and weight, the main con here is the high price of the camera and the memory cards needed to store your photos. However, if you can stomach £5000, the Nikon Z9 is an excellent mirrorless camera.

Sony A7 IV

Another versatile full frame camera
rating-star rating-star rating-star rating-star rating-star


  • Fast and accurate autofocus
  • Good handling and build quality
  • Very capable with both stills and video


  • Some video modes cropped
  • Fairly heavy build
  • Fast SD or CFexpress cards required for some modes

If you’re looking for another all-rounder at a fraction of the price of the Z9, the Sony Alpha 7 IV is a great and versatile choice. It’s also powered by the same Bionz XR processor as Sony’s high-end A1 camera. 

The A7 IV comes with a new heat dissipation system to keep it cool when recording video, a side-opening vari-angle touchscreen ideal for those looking to film themselves, and a sharp 3.69 million dot OLED viewfinder. 

The camera features Fast Hybrid AF with 759 separate detection points that cover 94% of the sensor’s imaging data and the ability to recognise human faces, eyes, animals and birds. We found this worked brilliantly, detecting eyes and faces from the side and bodies from almost any angle. 

The A7 IV is capable of capturing 4K video at up to 60fps, though you’ll need to go down to 24 or 30fps to get the entire full-frame field of view. That said, image quality is superb at 4K and the Slow and Quick mode makes is easy to record in slow and fast motion. 

Aside from the video limitations, the other con here is that the camera is heavy, weighing 658g before you add a lens.

Panasonic Lumix GH6

The best Micro Four Thirds mirrorless camera
rating-star rating-star rating-star rating-star rating-star


  • Massive range of video modes
  • Superb video image quality
  • No-limit recording times
  • Effective image stabilisation
  • Easy handling


  • Occasional autofocus quirks
  • Some features unavailable at launch

The Panasonic Lumix GH6 is the most impressive mirrorless camera with a Micro Four Thirds sensor we’ve reviewed and a great choice if you’re looking for something that is video-first but still offers great image quality. 

The GH6 offers a familiar shape and controls for anyone used to Panasonic’s GH series, but with the addition of a new cooling system and a new double-hinged touchscreen for greater flexibility than a regular vari-angle screen. 

The camera is capable of shooting 5.7K video at up to 60fps, and there are dedicated headphone and microphone ports, as well as a full-size HDMI output for external monitoring and recording and support for CFexpress Type B cards. There’s also support for Apple ProRes 422 HQ on board. 

The in-body image stabilisation offers up to 7.5 stops of motion compensation for stable video and the high resolution photo mode merges bursts together to capture 100-megapixel images. 

The autofocus is less impressive. We found it had a tendency to lose focus when tracking moving objects. This also isn’t a photography-first camera. While the GH6 can produce fantastic stills, if your main purpose isn’t video then you may be best looking elsewhere.

Fujifilm X-T4

A mirrorless camera with a retro style
rating-star rating-star rating-star rating-star rating-star


  • 4K/60p 10-bit internal recording
  • Intuitive handling
  • Impressive battery life
  • Stunning pictures


  • Doesn’t come with external charger

The Fujifilm X-T4’s timeless retro design makes it one of the best looking cameras in the professional market – and its specs are just as impressive. 

The camera benefits from a rugged magnesium alloy frame for weather and dust resistance and there’s a good number of dials and switches without making the rear of the camera cluttered. 

There’s a 3.69 million dot OLED viewfinder that covers 100% of the frame for a clear view to compose and review your images and a 3-inch LCD touch screen that flips out of the camera. 

The X-T4 also features new in-body image stabilisation and the autofocus and battery performance have both seen massive improvements over the X-T3. Face detection and eye AF are particularly impressive and the camera is capable of shooting at up to 15fps in a burst. 

The camera supports F-Log and HLG picture profiles and can capture DCI 4K/60p at 200Mbps with 10bit 4:2:0 colour internally. There’s also the ability to record Full HD video at up to 240fps for an up to 10x slow motion effect.

One con here is that this camera doesn’t come with an external battery charger, meaning you’re forced to charge the battery in camera. There’s also no dedicated headphone input, but you can monitor audio via the USB-C port with the help of an adapter so this isn’t a significant drawback.
