This lens was one of the most amazing optics I ever used. I earned lots of money making copies for a photo archive using this lens. Eventually I replaced it with the 69mm F 2.8 AF but great as it was it did not have the magic of the manual focus one. So much for progress. I just want to share these two examples shot on Kodachrome II on the Nikon FTn. BTW, Kodachrome II had it's own magical qualities. It's the only thing I miss about film.
