I need to get an adapter and start playing with some of my Nikon glass on the Fujis. I love my Fuji lenses — they are a big part of why I got into the Fuji ecosystem to begin with — but manually focusing with a lens that was meant to be used that way is a joy. Plus the optical shortcomings of the old vintage glass can translate into some unique and beautiful renderings if you’re open to looking beyond pure sharpness as the measure of a good lens.
