Bought this lens to use with my Sony A7R and A7S. It's a very sharp lens, but the depth of field at f/2.8 is ridiculously shallow. But it takes great pictures. Here are two recent examples shot with it on the A7R, around f/5.6-7. Focus and aperture work great, just be prepared for a fully manual lens. 10/10 would buy again
