I have an M10 with 90mm f2 Apo-Summicron M Asph lens.
I'm having difficulty focusing using the EVF Visoflex 020. I have read somewhere that the focus peaking works best wide open, and some have suggested it is best to focus wide open then stop down to the required aperture. I look at other images captured by the same lens/body and can only dream of getting anything that sharp. Obviously I am doing it all wrong. Focusing is fine on 50mm f1.7.
Any help appreciated.
