I have had my A7R for 3 weeks and used for tests and real world shooting, inc. night photography. Its not an action, street or holy place camera, too slow and noisy, but excels for landscapes / city scapes-love the DR, colour, resolution and handling. Big problem, which may be a rubbish adapter - Canon 15mm feye, Samyang 14 and Canon 17-40 very, very poor left hand edge, but right side fine. Any lenses 24mm plus fine. Exceptionally good results with Canon 40mm, 50mm F1.8II, Samyang 35mm, Canon 24-105L, Canon 70-200L IS, Canon 70-300IS, Tamron 70-200 F2.8 (non-VC), Nikkor 55-200 DX (full frame!), Nikkor 10-24 (APC mode only). All Nikon Dx lenses work fine in APC mode. Sigma 150-500 works with good IQ and OS, no AF. In fact, only AF on Canon 40mm and 70-200L, fails or rubbish in the rest. Not a full replacement for my 5D mkII or Nikon D7100, but for slow, tripod based photography 24mm + is amazingly good. Hope to get better ultra wide angle results in the future with new adapter, but suspect may need to wait for Sony FE. Oh, little Olympus 28mm f3.5 works, but not especially sharp but nice and even across the frame. Would like to see Voitlander wide angle results, anyone? Or experience with Canon 17-40mm?
