I'm using Canon nFD 85mm f1.8 lens on my E-P2 and getting some nice results. I usually use it at f2 as there is some ghosting wide open at f1.8 when there is a lot of light around. This lens is surprisingly contrasty even compared to some native m43 lenses. At f2 is nice and sharp, just snap on ND filter and shoot away. All the pics below were shot at f2, OOC jpegs (i-enchance mode).
