This week I bought one of these lenses for the intended purpose of creating some images during our rivers cruise from Amsterdam to Budapest. It will be used with my Df, and will be the only lens I will take. I know almost nothing about this lens, except what I have read in the form of brief reviews, and am looking for first hand reports and evaluations by forum members. It will be this lens, my second version 43-86 or my 50mm f1.8 pancake, f2 or f1.4.
