I like the 6D. For most of what I do, it does the job with no fuss. I like having the superfine screen for manual focus, too. So I can't see the point of the 6D2. I have a few AIS Nikkor lenses kicking around, I use them on the Canon as well. Is it "the greatest camera"? No. But it works, and I have a set of lenses I like in Canon mount, and I should get around to buying the TSE 24mm II soon - there are some unique offerings - as can be said for the Nikon side. I just wish a 1DXII or better sensor would get put into a smaller body without a lot of other features. Weight is a real issue, all the more if I am backpacking. A 110 pound woman can't haul unlimited gear safely.
