In my experience the A7 is capable of very sharp results with all MF
lenses, including zooms. Actually better then ever on a dslr.

However, you cannot trust 'focus peaking', but instead you need to magnify
the viewfinder image to get best results. It can be set to the C1 button,
allowing for an easy workflow.

Hope you try it again. For adapters that go to infinity, I can recommend this
brand
