Max from Texas here. I used the Sony NEX7 and A7r for the last few years and really thought they were superior to Nikon's 7100, 800(e) and other Nikons I tried briefly. My friend that had a 7100 upgraded to the D810 and in December we did a side by side comparison with equally Imatested Zeiss 135mm Apo-Sonnars. When we got in front of a big wide gamut screen I was floored. The Nikon files were much cleaner and had far better resolution than the Sony.
Before I finally sell the Sony off I am spending some time documenting the differences between the Sony and Nikon and am blogging it about it.
The Sony A7r is getting trounced by the Nikon.
I've joined this forum to learn more about operating my Nikon even better.
I wanted to post a link to the blog but wanted to be certain it wasn't spam first so I'm checking with Adam.
