I picked up a 210 mm Rodenstock APO Gerogon a while back on E-bay (dirt cheap) with the intent of using it on my 5 x 7 enlarger. It seems to work fine with that size negative. In doing some research, I now know that this lens was originally made for process work in the Graphic Arts Market. However, I'm also hearing about many photographers using it on their cameras for general photographic work . Does anyone know what kind of performance I could expect out of this lens both as an enlarger lens and a camera lens? My enlargements are rarely larger than 11 x 14, and I do primarily landscape work. For camera work, would this lens work better for long landscapes at infinity or for closer work?
