Hello... got my 5D Mk3 last week and have been playing with it to get myself used to it for a wedding shoot in 2 weeks time. Anyway, took about 350+ photos at the zoo today and found 4 photos that have some major problems with it (I say major as there's no room for mistakes when shooting weddings).
Anyway, please see the 2 attached files showing the problem.. Just not sure if its hardware-related or software-related that's causing this problem.
If you've seen anything like this before, please let me know. Thanks heaps.
