Am I the only one to think that 5d MK3 has very poor performance in shadows, even in low isos like 100 or 200 ? High color noise, weird noise patterns, vertical bands/stripes all without any pushing!!!
Straight out of the box the images look terrible in the shadow areas.
Why is that? I am very disappointed. VERY disappointed ...
Even my poor old 350d did better in that domain...
Is there something wrong with my copy or is it supposed to be like this ?
Welcome to the party .
There have been endless posts and whining about this since the very first RAW files were leaked (and going even back to the early 5D2 days). Yeah Nikon got like 3 stops better for low ISO shadows and got rid of all banding and Canon got rid of horizontal (while leaving vertical as bad as ever) and actually made the read noise per photosite at ISO100 the worst of any of their DSLR since the 30D, I believe. That said it's only a trace worse than the 5D2 in that regard.
The deep low ISO shadows of the canon dslrs look best with the 40D and 1Ds3 and maybe 1D3. The 7D,5D2,5D3 are probably worst with the uglies. The D800 is easily the best, althoguh almost any even semi-recent nikon is a lot better in the low ISO shadows.
Some of use tried to make a big deal of it before it would be too late but most got driven out of various forums for being whiners and babies and here we are, say thanks to the fanboys and helped make Canon think nobody cared.
The 5D3 did fix up the high iso shadow uglies a ton though, it is probably canon's best yet up there and probably only the D3s and D4 are better of all consumer DSLRs ever made (and the D3s is very low res). The D800 is right there too though or better at the lower high ISOs though.
I've said too much on this, way too much already, so I won't say more than what I just said above, which was already adding too much to all I've said.
