I love adapted lens composition. The Fuji's sensor is so clean and "capable" to begin with as it does not have the dreaded AA filter.
But when you put some other brand of glass in front of it (lens) the end result can be pretty rewarding. As you know, it's hit or miss, but that can be part of the fun.
Especially when you consider that these 'adapted lens' experiences are a manual focus mission.
Again-- nice work. I have never played with a mirror lens-- I bet Nikon has a dandy one by the looks of the image!
