A7 already is much better than the A7r with electronic first curtain shutter, making it quieter and with less vibration during the time the shutter is open. Same story with flash-sync.
Also I'm sure I've read at least one reviewer say that the A7s is quieter again than the A7 (ignoring silent shutter), although I'd love to find other confirmation.
A7R is way better with 36mp (compared to 24mp of A7) Also no AA filter for much sharper images, and full metal build (rather than A7 plastic)
hehe, just had to
Yes, but 36 mp and no AA filter are no use if you've missed the shot because the subject has moved slightly due to lag or if you have vibration. I actually think the lag/slow AF in the A7R is much worse than the vibration, but still I struggle with the idea its a "better" camera than the A7. I don't believe the AA filter in the A7 is very strong anyway, its certainly capable of incredibly sharp images. I challenge anyone to detect the fact some parts in the A7 are plastic compared to the A7R (the A7 feels more solid if anything, I think because its just slightly heavier).
The A7R
can make great pictures, but I'm not happy with the compromises around that. It strikes me very much like the early firmware X-Pro1, a beta camera put into mass production.
My A7R is likely to be ebayed soon, I plan to keep my A7 for a while.
in fact both us are right, if you want ultimate image quality go for 7R. Ultimate low light 7S, A7 is the most balanced body. For me i wanted the ultimate IQ, and ready to perfect my knowledge accordingly, actually love the feeling that I (the photographer) is the variable these days. The 7R is harder to use, so if you are just a weekend snap-shooter you wouldn't like it. It has made me a better photographer though, and the images i am getting blow my 5Dc and 5D2 away.
