I set the lens at the recommended starting point according to the link and loaded a roll of Kodak MAX 200 last night. Does anyone have any tips on using the EV system? Im pretty sure the original EV card for kodachrome will not be accurate, so will using an EV application result in more accurate measurements? From the minimal information available about what speed the fixed shutter is, ive heard 1/60 or 1/125, but i'm not sure which one i should go for.
