I finally got the Voigtlander Nikon F adapter for my E-PL1. I've tried the following lenses very briefly: AF 24/2.8--a bit slow for this focal length, but good quality and good focs ring. I will want to try the Panasonic 20/1.7. MF 35/2--awesome combination of focal length and speed, great focus ring. AF 50/1.8--Very nice quality, usefyl focal length, not the greatest focus ring. AF 105/2 DC--Outstanding optics, well damped focus ring, very shallow focus when you need it.
