The 5D Mark III by itself is a much, much more powerful tool than the 5D Mark II and 7D combined. If you know how to use it (which most critics do NOT) you would know this. If you are complaining about a black AF point, you really have problems to begin with in your photography anyways, so the differences between these cameras would be a non-issue.
Ah, another person who doesn't understand the meaning of 'sarcasm'. Sorry, was just poking some light-hearted humor at the "problem" at hand. (sigh) I guess that I
don't know how to use my equipment so I should just keep my posts to myself.
Or better yet... maybe some 5D3 owners out there, some of them happen to be "REAL photographiers", who are having a REAL issue with this. Or maybe this is kind of like those who compalined of a "soft focus" issue with the 7D. Plenty of people scoffed at the "problem" and said it wasn't real and that it was a user issue and not a hardware issue. Google it and see how many people had the same "problem". My own 7D had the same issue until I sent it in for an adjustment (under warranty), and now it works fine. Or maybe I just happened to "learn" how to take a photo in the week they had my Camera. (sigh again)
How about spreading some of your "wisdom" and help those who are having this issue instead of telling them that their skills "suck"? (my words)
