Canon announces EOS 1D Mk IV

Canon has today announced a long-expected major update to its flagship professional digital SLR, the awesome but ageing EOS 1D Mk III. After listening to feedback from the professional press, sports and wildlife photographers who are the 1D's main users, Canon has revamped all of the camera's major systems.

Top of the list of improvements is a custom designed 16.1 megapixel APS-H CMOS sensor, a big increase over the 10.1MP of the previous model. APS-H is slightly larger than the APS-C sensors used in the majority of digital SLRs, giving a crop factor of x1.3. The new sensor features gapless microlenses with less surrounding circuitry and more sensitive, high-capacity photodiodes, and an ultra-fast eight-channel data path feeding into dual DIGIC 4 processors, enabling 10 frames per second continuous shooting at full resolution.

Another major component to see an upgrade is the autofocus system, which has been replaced by a new 45-point array with 39 f/2.8 cross-type sensors for improved speed and accuracy especially in low light or with moving subjects. It is linked to a 63-zone light metering system, with multiple metering modes including AF-point linked and multiple spot metering options.

Other upgrades include a standard ISO range of 100 to 12,800, with an extended range from 50 ISO to an almost unbelievable 102,400 ISO, the highest sensitivity ever on a Canon camera. It has an intelligent noise reduction system to keep chroma and luminance noise to a minimum, while maintaining colour balance.

Like the previous models in the EOS 1 range the MK IV has an exceptionally strong magnesium alloy body with 76 rubber seals fitted around the controls and cover seams, making the Canon EOS 1D MARK IV dust and water resistant when used in tandem with Canon's range of weather-resistant EF lenses and Speedlite EX flash units.

Of course no modern DSLR would be complete without video recording, and the EOS-1D Mk IV is the latest to jump on the HD bandwagon. It can shoot 1080p high definition video at 30, 25 and 24fps and 720p footage at 60 and 50fps. It also offers full manual exposure, and a programmable control button to allow instant movie recording.

Other improvements include the 920k Clear View II monitor, in which the gap between the display and its cover has been filled with a transparent material to cut down on reflection. The previously acrylic cover has also been replaced by reinforced glass, providing strong, scratch-resistant protection for the screen. The Mk IV also features integrated sensor cleaning, which automatically eliminates dust on the sensor - ensuring reliable image quality when shooting in dusty environments.

Of course a camera like this doesn't come cheap. The EOS 1D Mark IV will be available from the end of December 2009 priced at £4499.00 RRP inc. VAT.

Wealth Warning!!!

If you live in the UK do not buy this camera. It&#8217s on pre-order in the US for $4999 (£3048) and in the UK for £4499. I used to get really annoyed when Apple pulled this stunt and we should all boycott Canon until they treat the UK market with some respect. I know that in a few months the UK price will be on par with the US but it is still piss taking by Canon. Or is it because we have a reputation for being happy (stupid)at paying over the odds to be early adopters?

If I were going to part with this sort of money, i would definately want a full frame sensor at least! Especially as this is aimed at the professional market! Not only that, but when you comapare the pixel rating to the 5D MK11, at 21MP, ( granted, pixel rating isn't everything to achieve better quality pictures, but it helps) it's not a particularly high pixel rating these days. One thing that does impress about this model, ( which still appears to be rare amongst digital SLR's)is the claimed 10fps burst speed on full resolution setting.I don't know why Canon don't start incorporating more than one digic processor in most if not all of their other digital SLR's if this is what it takes to get fps rates and reasonably high pixel rates in the same camera to achieve decent level for sports photography etc.

Agreed. The UK 7D is still on parity with the US @ £1699.

It's very annoying, but it happens across the board with every single product on the planet. From washing machines to computer parts, from housing material to cars...everything (apart from phone contracts & bread- i'm sure there's more too!) is cheaper in the US and they have a higher mean income per capita per head compared to the UK. (believe it or not!)

But I prefer living in the UK, and I don't have to feel like I should automatically tip everyone even though the service was pants, and i'm none too partial with their military policing either...so I guess i'll just live with it.

But still, it's sooooooo much cheaper there! :(

Pfftt! Weekend break for two to New York must be include with each UK model. Just get a Nikon. Simple.

It's a lotta lotta dosh, but remember these are a lot of pro's who go through a 1D every 18 months and whilst they might not rush out to immediately upgrade this will form the logical replacement when needed.

@Mike - I kind of share your point, but for sports and wildlife pros (where this is aimed) the 1.3 crop factor is quite a boon really. Makes your £7k 600 f/4 into a nice 780 natively... The 5D MkII has a different market, where FF sits more logically...

Steve Ayres,

Agreed for wildlife photography, I agree the crop factor is a plus, but for one who wishes to get one SLR for the majority of his uses out of a camera( I simply cannot afford and don't want more than one SLR!) this is definately my preference. There are undoubtedly pros and cons for full frame and non full frame sensors, but for me, at this sort of dosh level,if there's no full frame in it, I definately won't be parting my hard earned on this one, 10 FPS or not!
