Is it the camera body or adapter?
I have NEX-F3, and I bought LA-EA3 adapter to use my SAM 50mm F/1.8 DT lens and Sony 85mm f/2.8 SAM lenses. However, the focusing speed is horribly slow on NEX-F3. I wonder, is it because of my out-dated camera, or wrong adapter? Which one would provide a significant improvement? A newer camera or a different adapter?
