Re: Fun with the A7/7R
Could you post a pic of the lens mounted in an adapter, showing the rear?Had a play around this arvo to see if I could provoke CA. It is still there from f2 to about f4. However I had to point the lens at an area of very high contrast (slat blinds with Australian midday summer sunlight coming through) in order to get it to become visible. I think the reason I haven't really noticed it is that with 36MP the area of the image made up of CA is small enough not to be a real issue unless you go to look for it. I can see it when I have the focus magnfier on, but not with the EVF at it's normal resolution.
Edit: Had a play with my CV 35/1.2, ZM 50/2 and even a Nikkor 85/2 SLR lens that a friend lent me and they all exhibit CA wide open to a degree. In the case of the Nikkor it never gets any better. With the Planar and the CV 35/1.2 it's gone by f4 similarly to the ZM85.
