Some in the coming days and weeks i will be posting my review on the 5D Mark III and sharing detailed analysis on the picture quality, video quality, battery testing, Eye-Fi testing, Shutter Speeds/Sounds, Memory card writing speeds and as many features as I can test before I have to send back my rented 5D Mark III (you think LensRentals.com would notice if I sent back my 5D Mark II instead of the III?)  I will also be comparing the 5D Mark III to my copy of the 5D Mark II that i have had for 3 or 4 years now.
