I am coming from a t3i, I want to go full frame. I take a lot of sports shots, nature, and just everyday walk around photography. I am wondering what would you guys think of either the 6D, 5D Mark II or 5D Mark III. Would it be better to get either the 5D mark2 or 6D then later in life upgrade to the 5D Mark III? Or keep my t3i and save up and jump to get the Mark III?
