Perhaps, I just got one, put through test roll, and seems that overexposing one fstop helps (thanks to ISO dial, which I miss on Epic). Test roll were el cheapo GRAIN400 from trashbin, so I'll try with slower and sharper film.
I have to admit, that even I will not shoot tons of HF, I love how it's designed and operates. Btw it darn fast - I shot serie with passing cars and most of them are taken before they fully enter frame - I operated like I do with Epic. Non-moving lens on AA35 matters !
