Has anyone who has bought either the A7/A7r come from a full frame DSLR? I've been tempted to downsize from a D800 particularly considering that I mostly use 35mm all the time.
I too went from 5D mk1 to A7.
I had Sigma 20mm f1.8, 50mm f1.4, 85mm f1.4, 150mm f2.8, 12-24mm, Canon 20-35mm and 70-300mm.
I now have 7D+ 28-70mm (unused apart from a few test shots around the house when it first came.)
Minolta 24mm f2.8, 28mm f2.8, 35mm f1.8, 50mm f1.4, 85mm f2, 135mm f3.5 and a Tokina 70-210mm.
I'm very happy and although the 5D was a nice thing especially with the Sigma 50, 85 and 12-24mm lenses the A7 with any lens (the 50mm seems to be my fav) is just a joy to use. It's about the same size as my G1, the dynamic range is amazing, the hish ISO performance is fantastic and the images at low to medium ISO's are... well, I couldn't ask for better image quality and the images can be processed very heavily in CS5 before they start to fall apart.
The only negatives for me are that I'd love a fully articulated screen as per the G1 and I'd love the ability to TURN THE SCREEN OFF!!!!! without diving into the menu.
I may go for AF primes at some point especially if a longish f2.8 macro comes along, something in the region of 100mm, but right now MF lenses are IMVHO a joy to use and so much so that when I use AF lenses now on my G1 I worry that the camera isn't going to focus on exectly what I want
