I shot one of my favorite Russian watches with my Pentax 645 and Nikon 75-150 Series E. The lens adapter was made with a 645 body cap and Nikon rear lens cap glued together. That combination vignettes, so I had to add a 12mm ext tube, and that just about took care of the dark corners. Ilford HP5 sent to DR5 lab for transparency process. Copied with D300 and 60 AFD micro. I like the crop better.
