I have used this EF to Sony E mount adapter, and it feels very tight. The auto aperture is always lost, and I can only see 'F' displayed. Every time I need to remove the lens and readjust it, and the autofocus is also not accurate and very difficult to focus. This doesn't work for me, as I have tried different lenses. I need a refund because I don't have any use for this. It's a waste of money. I wish B&H would talk to the seller and help me solve this issue. I need a solution
