Hi folks, Newbie question re Focus with adapted lenses. I'd like to buy a long, fast legacy lens it two for my e-m1, but I find it very difficult to focus manually without peaking. My old Minolta lenses are very challenging to focus. Might be my 50-something eyesight adding to the challenge, so I need focusing aids. Will any legacy AF lens with electrical contacts provide peaking with an appropriate adapter? Is that the best approach? I can't imagine trying to manually focus a 300, or 400mm without aids. Thanks for any advice.
