yep, that's the one I saw. It may very well be that the 36mp sensor of the A7R, with no AA filters does not quite work out for the lens. My idea was to have a really small lens that fit my need for wide angle on the A7II. It may be that is all it works on, but I do like the manual focus lenses on the camera, and the
size of the MF lenses are a plus.
