Im looking at a new camera and have decided to swap from canon to sony due to the much bigger lens ecosystem that is out there and i cant decide if i want to go the mark 3 body or the new mark 4 one, so far im liking the mark 4 body since it has a much bigger buffer vs the mark 3 (i shoot alot of wildlife and transport so a good buffer is important for me and right now its painful on my current camera) so im throwing it out here, if you own one or both of these camera's please let me know what you like or dislike about them.
