This has been a GREAT thread! Of course, it took me an hour and a half to get from start to finish and I wanted to yell "STOP" to you guys so that I could catch up but could see the page numbers growing...Anyway, I have the 5D MarkII and am looking at getting a second body, well, I guess technically third since I also have a T2i but I rarely ever use it anymore. Oh, and btw, I loved someone's earlier comment (like half-way thru the thread) that said the Rebel users were out honing their skills etc....SO true. No one should be knockin' the Rebel shooters, they're out there learning and improving, not judging anyone else and clinging to their own opinions. Anyhow, I debated the MarkII or MarkIII last year and decided the MarkIII wasn't worth the additional cost. I just started researching the 6D and am now completely sold on it. It's EXACTLY what I need for my photography since in my case, noise is VERY important to me and auto focus really isn't. Thanks for helping me make my decision everyone!
