I would think this has been done to death, but my search didn't find this exact thread (but, my luck at POTN searches aren't the best mainly because of the many possibilities for the names of the cameras (1D3, 1D MarkIII, 1D Mark III, 1D Mark 3, etc)
Anyway, I'm curious to hear from people who have owned the 1D3 and then switched to a 5D2 if they thought they made a mistake, what they miss, what they prefer, and in general if the probable IQ advantage of the 5D2 was worth the loss of the amazing ergos/build/features of the the 1D3.
For me the 1D3 has me spoiled for features and build, and shooting RAW and using Pixmantra's custom 1D3 two stage NR the high ISO noise of the 1D3 is as good, if not slightly better, than anything I can get with the 5D2 RAW files I've played with (I keep saying Pix is a genius). The original 5D surprisingly never had "great" dynamic range for FF (according to most numbers, DR was quite average, about the same as the 20D), and I think the 1D3 may be the current leader in that department (although, with CMOS sensors the real world diff from camera to camera probably isn't as big as some people think). Is the 5D2 noticeably better/worse?
I'd like to hear some real world examples/comparisons from people who have owned both rather than rely on theories about pixel density, blah blah.
I'm thinking of doing a bit more stock/studio, and less sports, so that's why I'm asking.
Again, I'm not really interested in hearing theory or starting any flaming, I am just curious to hear some personal experiences.
