I have been shooting EFKE films since the early 80's. In fact I still have around a 100 rolls that expired back in 1988 but it is deep frozen and works just great.

My favorite is EFKE 25 (RB14) and I shoot it at an EI of 25 and develop in Rodinal 1:100 for 20 minutes at 68F. Magic combination.

I also have RB17 and RB21 emulsions.

My closest supplier is the Looking Glass in Berkley, CA
