My conclusions are that the CA is nothing like so bad in C1.
I have a demo copy I think for OSX so I can re-open the RAW files in C1 to see the differences, hopefully later this PM if I find the disc!
I cannot think of a repro circumstance where this fringing would be noticeable and I wonder if we worry too much about faults which are only showing because of the increased detail we now expect.
I agree with this statement so much as I feel photographers are more anal than ANY other viewer BUT, in this case it really is bad. I could send you a RAW file if you wish to look? In fact you maybe able to tell me if C1 and CR give different results if I can't find my copy.
The red highlights are surely another issue and not CA. These are virtually non-existent with C1 although I can see them clearly in the preview. After processing they are not there. Are they caused, in your case, by slight camera or subject movement?
In my case, they are there before and after processing and of course any CR sharpening really makes it worse. It also definitely prints up on 10x15" SFA paper and looks just as red. Most of my subjects are seas and crashing waves so of course movement is unavoidable. This is why unless I can find a lens that doesn't cause a problem, then the 1DS is just not up to the job. I can't spend hours in PanoTools for every sparkly image. I'm wondering id users of the 1D Mk2 have noticed any such issues with the slightly smaller chip?
Many thanks for your input Bob, and if I could send you a file I'd be very interested in your comments.
