I have this lens, apparently a soft focus. The lens is approximately 180mm, and the elements are in brass mounts. I'm not sure if the elements were fitted into the Copal 3S shutter at the factory, or were retro-fitted. At any rate, it is a very good job. The glass is exceptionally clean. Both front and rear elements are 58mm dia, and overall length is 74mm.
Here is the lens: https://picasaweb.google.com/1041315...MOE95qO5IX46AE
I made some photos with it, at f/4, f/8 and f/22: https://picasaweb.google.com/1041315...MD1lMeOwNuClAE
What do you think this could be?
