I use an A-6000, recently bought a F-S 10-18mm + Viltrox Canon to NEX iii Adapter. I noticed that: Hope someone has a solution to these problems. 1. @10mm to 15mm zoom, the aperture works fine. But when zooming to about 16mm to 18mm, the aperture max becomes f11 instead of f5.6. 2. The lens manual focus doesnt work most of the time. I have to unmount the lens and then mount it again so that it will work.
