Here are a few pictures. Enjoy!
That silver lens is the one that took the shot above. I managed to obtain the bellows that had been with it and that went over the front of my camera and kept a lot of light out of the way. I think, given the right subjects, it is a viable way to take photos. Also, it challenges you to go back to the basics of setting your own shutter speed and making educated guesses. Oh, and the shot below was taken using one of those lenses from an enlarger. They were two 75mm lenses and one 50. The silver one was made in the USA (probably in the 1960s) and has 13 blades in its aperture diaphragm. One was made in Germany and has 6 blades, while the Japanese made lens has only 5 blades. The 13 blade makes a lovely round aperture.
