Well well well. In my quest for proper testing among the 3 various cameras, I have had to consider a 4th, the 1Ds Mark III and I'll share why. A problem was found with the 5D Mark III. It could be a serious problem, and I have confirmation from several other photographers. Daytime, ISO 50-400, both the 5D3 and 1Ds3 are comparable. In fact, after post processing, yes the 5D3 looks just a little better. Now go shoot with the 5D3 under a tree in the shade, or indoors in tungsten and fluorescent lighting, and now you have green hues to the shadows and/or areas around highlights. I have some photos I'm going to share. This is a prominent problem if you examine my photos and another photographer's photos. I have many of them from both bodies I own.
Now, take the 1DX. You don't see this, nor do you in the 1D4 or 1Ds3. Seems a slight color accuracy problem with the 5D Mark III. It is also very difficult to get rid of these hues in post processing as I thought it was simply the white balance being slightly off. It isn't. You cannot adjust color temperature to get rid of the problem. The 1D bodies are not showing this effect.
I'll have some photos I'd like you to look at and evaluate. What this may mean is that the 5D Mark III is a much, much better daylight camera despite the high ISO capabilities than a low-light camera regarding color accuracy. Time will tell.
