I have a lot of Nikon lenses- somehow managed to pickup 30 Nikkor Rangefinder Mount lenses between the S-mount, Contax RF mount, and Leica mount lenses. But I REALLY have a lot of F-Mount lenses. I shot mostly with Nikon SLR's from 1978 up, used an F2AS and F2Sb for a long time. I picked up a used D1 about 10 years ago, but never "warmed up to it". Worked with AI lenses, but just not the same as the F2AS- and did not like the "mini-viewfinder" 1.5x crop factor. This past Summer I used the EP2 with the Nikkor 300/4.5, did not have an easy time with the focus. The DF caught my attention, checked one out yesterday at Photocraft, a local independently owned camera store. I did my part for Small Business Saturday. So far, focus with the 55/1.2 wide-open is easy and fast. For anyone that has used an FE2 with a B2 or E2 screen: about the same. I have that combo as well.
