For static shots I agree, sony is much smaller. Let us know how well it does for action/sports compared to that 5dmk3.
lol the 5DIII is my work horse, and a damn good one. say what you will about the 5DIII's sensor, but the 5DIII can handle just about anything you throw at it.
The a7r will never be a replacement for it. It's works for casual shooting, but I'll reach for the 5DIII for anything outside of that.
I mean, I see your point, but the lenses you chose are a little bit deceiving. you chose a huge 1.4 prime. put a 2.8 prime on there and the size decreases significantly.
i'm not trying to knock your choice, hell, I wish I had the money laying around to try it. I just don't see how carrying a smaller DSLR is much more convenient than a slightly larger one. they both are bulky and large, don't fit in pockets, require bags, etc. what about the other lenses, or flash?
The size and weight difference is pretty substantial in real world use. No it won't fit in a pocket, but its not nearly as bulky and clumsy as a typical full frame DSLR. When shooting casually, I usually stick with a single prime, and wear the camera on a Joby sling strap (don’t usually bring a bag). I don't usually bring a speedlight when shooting casually, as I’m less concerned about taking flattering portraits, and more concerned with capturing moments in their natural element…which usually means natural light.
I used to lug my 5DIII around casually with a sling strap like this, and while its a comfortable set-up, it is pretty cumbersome (constantly trying not to bump into things), and it draws a lot of attention to itself. It’s nice to “wear” a smaller, more discrete camera out for the day. It also doesn’t get the attention that my “pro-looking” DSLR does. I also like that it fits in the shoulder bag I bring to work, which gives me more opportunities to shoot, without having to compromise on the sensor.
The 35mm prime works for my uses. The 55 1.8 for the A7r is still pretty compact, and still offers a size/weight advantage over a typical full frame DSLR:
