If still can’t decide whether to pull the trigger for the Canon 5D Mark III or the Nikon D800, maybe this video will help you decide. Dave Dugdale from Learning DSLR Video went out and bought both bodies and did a series of test (mostly for videos) to compare the two. I would say that this is one of the most objective and thorough comparisons I’ve seen. As I’ve said it BEFORE, if you’re already locked in with one system, I don’t think you’re going to switch. If you’re interested in reading the full writeup of this video, check out Dave’s blog post HERE.
I’m not going to lie, his monotone literally made me fall asleep towards the end of the video.
