All other image quality aspects are up to Canon's usual high standards, so top marks go to the 5D Mark II in this department.
#Canon mark 5d ii review iso
We haven't reviewed the Sony A900 just yet, but we hear on the grapevine that it starts to get noisy at around ISO 800, which means that the Canon EOS 5D Mark II would seem to offer the best of both worlds. Canon seem to have matched the low-light performance of the Nikon D3 and D700 whilst substantially increasing the resolution. There's virtually no visible noise at all from ISO 50 all the way up to ISO 3200, with even the three faster settings of 6400-25600 producing perfectly usable images. The new 21 megapixel CMOS sensor and expanded ISO range thankfully haven't compromised image quality in any way, quite the opposite in fact. Much more successful, and I think where the real strength of the Canon EOS 5D Mark II lies, is the amazing combination of high-resolution images with low-light performance. The SLR format just doesn't lend itself very well to shooting video handheld, really requiring a sturdy tripod to achieve good results, which obviously limits where you can take the Canon EOS 5D Mark II and what you can achieve, plus the inability to auto-focus quickly and effectively using the contrast-AF system will frustrate most casual users. Experienced videographers will no doubt be chomping at the bit at the prospect of being able to use all those different lenses in combination with such a high-quality sensor, but for the rest of us mere mortals, it may actually prove more frustrating to get some decent footage of the kids than by using a dedicated video camera.

This is the key phrase - "film-makers" - that you need to consider if you're attracted by the 5D's video functionality.

#Canon mark 5d ii review full
The ability to shoot full HD video with a DSLR camera has gained the 5D Mark II a lot of press coverage in the weeks leading up to it shipping, fuelled by the release of some jaw-dropping video footage from independent film-makers. Your £2000 / $3000 purchasing decision is made much harder by the fact that all three cameras are quite different to each other, with the 12 megapixel D700 putting the emphasis on continuous shooting speed, the 24.5 megapixel Sony A900 on sheer resolution, and now the Canon EOS 5D Mark II throwing video into the mix. The high-end prosumer DSLR market is an interesting place right now, with three cameras - the Nikon D700, Sony A900 and the new Canon EOS 5D Mark II - all fighting it at a similar price-point.
