Foma 400 is my main goto film in both 120 and 35mm, I love the tonality of the film, as far as grain goes yes, the 35mm can be very grainy, but bI rather like the grain , the 120 is not to bad, grainier than ilford/kodak films, but at the degree of enlargement I don't notice it on 120. I develop it in stock D76 for 8 minutes and get lovely sharp negatives that print well, and I have printed up to 20/24 with it, although normally my standard paper is 9 1/2 by 12, I also develop it in Rodinal 1/50 and it is even better tonality and very sharp indeed, as far as speed I have shot at box speed, but prefer 320,
