Is the 5D III any worse than the 1Ds III for the highlight details and shadow details?
I read that the color was the worst ever in a Canon DSLR. Is it obvious or is it feasible to mix and match images from 1Ds III, 1D IV with the 5D III?
I had a 5D II and the camera was rather rough to operate with poor AF. I think the AF of the 5D III is considered to be better, but is it acceptable for tracking outer/upper points at f/5.6 compared to 1D/s series II/III/IV?
I can live with whatever new weird...Show more →
It focuses well (sometimes the very outermost column might get a little dodgy with certain lenses). Mostly it does very well but the DR isn't that good for this day and age, it is a lot less than any recent Nikon (and even some from a few years back) and a bit worse than the old 1Ds3 in that regard as well as 1DX or, it seems, even 6D, heck it's actually a hint worse than the 5D2 in that regard (also you'd never notice the difference even with peeping). If you could live with the DR of your 5D2 then you can live with it on the 5D3 since it's virtually as good at lower and mid isos (and at least 1/2 stop better DR at high isos). Outer points are a lot more grabby than on the 5D2 and the center is even better (super good when paired with one of the new lenses with the ultra precision mode that the 1DX and 5D3 can take advantage of, so far focusing is magic with the new 24-70 II, you can get over 100 shots in a row in focus at f/2.8 even with indoor lighting plenty of times).
UI is sort of like on the 5D2 only even better and more natural and quick to use. C1-C3 can auto-update, quick button, tabbed menus, instant jump to 100% review and back, etc.
Oh the one other negative, along with the DR at low ISO for this day and age, is the lack of changeable focusing screens. Oh and the color filter is yet even more color-blind under natural lighting (but about the same under tungsten and such), what difference this makes is hard to say, it would take a lot of tricky work to sort out what, if anything it means in the real world, it did get one of the worst color discrimination scores though under natural lighting, that said who knows which shades it is worse at and whether it matters, it might be better for some colors and then much worse for others, not sure how it pans out, might not be any single answer and could even depend upon exact lighting and subjects. The new CFA also increased color noise, although the new sensor is a bit better so that is probably a wash in the end.
But otherwise better AF all-around, better built, better UI, movie mode got rid of moire and aliasing (although still not the sharpest tack on the block, although it is a natural look and not digitally crisped looking), mirror black out is less, fps much better, shutter trigger reacts more quickly. High ISO is modestly better, a little bit better SNR and less banding at high ISO (which can sometimes make a big difference at the much higher isos, if the images have large parts near black, it can look OK on the 5D3 when the 5D2 may be too ugly to use with banding and junk, so while the SNR is only maybe nearing 2/3rds of stop better at best sometimes you can go well over a stop better if the image is a really tough one just because the darkest parts might go to junk on the 5D2 but manage to be passable on the 5D3, so the 1.5-2 stops better is mostly hyperbole and not remotely true and yet.... for some some that can be the case, most of the image might only look modestly better in terms of noise but sometimes you can get nearing 2 stops better just because certain shots won't be ruined by junk even if the rest of the shot only looks modestly better).
None of these digital cams is any better or worse at highlights than any other, if you expose to save a highlight then it is there, if you don't then it is gone, they are all simple linear capture sensors (well maybe there were a few of those weirdo Fuji sensors and such). (Well I guess if the filters were super-unbalanced maybe some might blow one channel sooner relative to others. But in the end you expose to to not clip any channel of anything you want and that is that, it all falls to the shadows and how cleanly they can be read.)
