I purchased this FM2 at a camera fair around 25 years ago and it has served me without fail ever since. It is my most “nostalgic” camera. It hasn’t gotten as much use the last few years due to my growing collection of cameras, but I always take it out again eventually.
Usually I have the 50/1.8 attached which is compact and a wonderful portrait lens, however this time I grabbed the 55/3.5 macro, which is a great macro lens and a fine all rounder.
I used Acros pushed one stop to ei200 developed in HC-110 dilution E (1:47), developed for 7 minutes at 22 degrees C. For Acros at ei100 I would normally develop for 7 minutes at 20 C, and I saw on the Massive Dev Chart that someone recommended 7 minutes at 24 C for ei400 so this was a guess but it worked out fine I think.
I am cognisant that since getting this bottle of HC-110 my use of caffenol has nearly stopped. I also have the ingredients for D-23 waiting in the wings but alas, the corruption of convenience. I think some of it has to do with my concern about the HC-110 expiring before I get through it. Due to the dilutions this stuff goes a long ways!
