One can never have too many 35s or 50s!I'm using the FE35/2.8, have a FE55/1.8 coming in (very excited about that one). The jury of one is still out on the 35mm... I think I'll like it for convenience and it does look good closer in. For distant horizons, not so sure. Fortunately that's no really an issue for me.
I'm also shooting my old C/Y Zeiss and Nikon Ai/Ai-S lenses that I've been hanging on to, just waiting for an adapter to show up so I can slap on the Nikkor 20/3.5 28/2.8 50/1.4 85/2 135/2. Manual focus on the A7r is easier than on the GXR and I credit that to the much, no, infinitely (!) better viewfinder.
As I'd sold my Zeiss ZM Biogon lenses, I'm sitting on the side lines waiting for the smoke to clear with respect to rangefinder glass, especially wide angle lenses, on the A7r but will no doubt pick up a couple of focal lengths for more portability. Am really liking the ZM50/1.5 Sonnar on the camera but don't own one at this point... and not sure I need yet another 50mm kicking about. Ok, maybe.
It would be less of an issue further from subject tho, yes?nice dog chris. however your photo illustrates a potential difficulty with these cameras, namely the incredibly thin DOF and its effect on low light photography, especailly as they have no IBIS. my estimate is they lose 2-3 stops to m4/3 and 1-2 to apsc in DOF. that could be a pretty big deal when the DOF/shutter speed you need puts you at 3200 on m4/3. to achieve the same result youd be shooting at 12,800! i do about a third of my stuff in low light and this issue has stopped me in my tracks at this price point, even though generally the results these cams produce are excellent.
