Like title says, any low iso comparisons? Like side by side same image with both cameras? I've seen some comparisons in videos, but its hard to really appreciate quality in a youtube vid. I'm trying to decide if I should start lusting after the 1dx, or just be happy with my 5d3. I've always liked the idea of the 1d body style and durability, but i need some more info. Does the 1dx have more DR at iso 100? Is the banding any better?
no i haven't, although i did look at black frames a bit to measure read noise and to look at the banding patterns
the 1DX has a little bit less read noise, bit not a big deal less than the 5D3
it has a fair amount less banding, but still a bit more than the 40D or 1Ds3 (it has a bit more horizontal than the 5D3 which has none of that, but definitely less vertical which the 5D3 has quite a lot of, although the 1DX still has some; 1Ds3 has a little bit of horizontal but basically no vertical, now if they could only combine the 5D3 and 1Ds3 they'd be set for banding ;D although the read noise would still be way higher than exmor sensors or even the best non-exmor sensor in that regard, the one in the D4)
I'd say it has somewhat more usable low ISO DR but it's not a huge amount more like say a D4 or D800 or the like would offer, so yeah it would handle pushing around somewhat better than a 5D3 most likely, but not OMG! so by any means I wouldn't think, better in a noticeable but modest sense most likely.
Some of the Nikon are like 2-3.5 stops better than the 5D3, the 1DX is probably, at best, 1 stop better usable and perhaps only 1/2 stop so (ignoring banding, it is definitely not more than 1/2 stop better).
1Ds3 still probably has the best ISO100 by a smidge over the 1DX when it comes to Canon DSLR is my best guess
