A shot from some efke KB25 film - I've only tried one roll, but I like 
the results very much. It's a film that's apparently made similarly to the films of 50-60 years ago, with high silver content, and of course it's ISO 25 so the grain is tiny and it's really sharp. I got it processed by a place called dr5 in Denver - they process regular B&W film to make positive slides, which project extremely well and scan well too.

Taken with my 1N and Asahi 135mm 3.5 Super Takumar, of my M3 with Voigtlander 35mm color-skopar.
