5DIII same ISO performance as 5DII

<< < (9/10) > >>

people i know who have the 5d3 say it is a stop better.... 

swrightgfx:
Not really the place for it (other than the fact it would result in greatly improved ISO performance), but I think 362 would be lovely. That said, I would much prefer 6x6 or 6x7 medium format, but neither will probably spawn from the Canon stable.

It would be nice to use all my Noritar lenses on digital though, even just to see how they'd perform - would require a customised breech-lock adapter though.....

You dismiss the silicon waste too easily. A 43mm square sensor will have an area slightly larger than a P45+ digital back and be considerably more expensive to produce compared to a FF sensor.

rhommel:
in terms of high ISO performance, I can definitely say that 5D3 outperforms 5D2!



Natural Light
Canon EOS 5D MK III + 70-200 F2.8 L II IS
ISO 12,800
1/800
F2.8

there's no way my 5D2 could've taken that shot with less noise

Why do we care about vignetting at capture?  Why not have a 43mm square sensor, and just accept major vignetting at capture, but you've got the entire image circle.

If the viewfinder doesnt become square too it can get really annoying to "fix" ur composition of every photo by cropping. Plus i personally dont wanna crop every photo post.
