Does anyone know why Sony (or 3rd parties) can't make a better adapter for their A-mount SSM and SAM lenses? For example, the relatively inexpensive Sony 28-75 f2.8 is a really good lens. I've tried several copies and they make sharp, contrasty images. However, the AF on my E-mount bodies (a9 & a6500) is hampered by the paucity of focus points. The limiting factor is obviously not the bodies, and I don't think it's the lenses. It seems to be the adapter!
I have always used Cannon products but recently got into a videographer position in my career and have heard that Sony was great for videos! I purchased a Sony A7RII and currently edit on a Macbook Pro using Premiere Pro CC. When I take the video and play it back on the camera, it looks great! However, whenever I upload to my computer most of my shots have the "double vision" look to them especially since I film a lot to do with sports. I was wondering if there was a way to fix this?
