Hi, I have bought a Nikon 14-24mm 2.8 to use on a Sony A7R with manual focusing using live view.
I am finding that the marked distance scale is very inaccurate, especially at the wide end, improving somewhat at the longer end. At the wide end I get a focussed result for distant objects (30 meters away) when the lens scale shows only about one meter. Is this typical, or does the lens have an issue? For what it's worth, the lens sharpness seems ok, even wide open it is very good in the center, and not bad in the corners for such a wide lens (but clearly softer than the center, in agreement with the MTF curves I've seen). I've tried several different adapters and I don't think they are the problem (other lenses on hte A7R with these adapters are fine). I'm assuming it is also expeceted that zooming in/out causes significant focus shifts with this lens? Any help much appreciated.
Thanks.
