Is the mount tang at left bent?
Do you mean the one at the 6 o'clock position? I agree -- it appears to be distorted.

The lens was recently CLA'd (see original post) and the supplied photos show a clean mount.

Perhaps, but you never know. More important is the internal contact for the A position

I just took a closer look at the supplied photo. Is the mount tang at left bent? If so, that might be the source of your problem if the lens is not seated flat onto the camera.

Good catch. It should be possible to confirm this by simply pushing on the lens back to the mount and check if the lens responds with the aperture value

I was thinking the one at 10 o'clock, but the other looks suspect too.
