I love Efke films! R25, R50 and R100. Extremely fine grain and the conversion of colors into greyscale is great. The slow speed films are ortopan-chromatic. R100 has a little larger grain than APX100 and Plus-X, but I like it. It's hard to go wrong with R100, it's so forgiving. Much more so than the APX and PXP.(posted 8194 days ago)
