However it starts to be a bit outdated in ISO performance. I have 1d MK3 at work, and recently bought 5d mk2 for personal use (the 1d was also my old and used it for many years). And i can say that the 5d mk2 beats 1d in ISO performance, and i prefer it in general, even tho the 1d is so good to use and everything else in it I did like the feel of that camera design. While I never owned this one, I did have a a 1Ds ii and later a 1Ds iii. I still use an original 5D, and my modern computer with LR flies through the processing of its RAW files, unlike my Fuji XT2 raw and my Somy A7R3 raw. Something to be said about Canon’s old sensor look before you even processed it. The recent introduction of the sporty Canon EOS 1D Mark III marked a new era for DSLR's with its superb image quality. Especially it's quality at high ISO's, Digic III processor and blistering speed. Now Canon has finally brought these two cameras together with a newer, faster, techno-pumped monster. One that rivals, if not betters, medium Canon EOS-1Ds Mark III. move left: move right: move left: move right $4,375.00. Check prices. Read review Aug 18, 2008 Oct 18, 2011 The 21.1 mpix might be nice, but only in low iso ranges. It was not a secret that reducing the pixel size to 6.4microns would seriously reduce the ability to shoot at high iso ranges. The 3200 iso test-shots confirm this by tons of noise. But anyway, who needs 3200 iso. Pixel area difference: 1.59 µm² (3%) A pixel on Canon -1D Mark III sensor is approx. 3% bigger than a pixel on Canon -1Ds Mark II.
