Such an amazing place. Love the pics you've been posting. Have you ever tried the Sony NEX cameras? I use one for all my commercial work now. So much smaller than 5D and looks just as good (almost)
I had a NEX 5R that I really liked, but it was a tiny bit bigger than what I wanted to bring on rides, so I sold it and got the rx100. However, I did just pick up an A7 as an all-around camera!
Also, lol @ 13K feet of elevation gain. Probably only a few hundred feet. That's what happens using the iphone app through narrow cliff walls, I guess.
A7 is pretty sweet.
Enjoy your adventures. I dream of what you're doing, but have to pack it all into a few hours on a Sunday (kids)
