Hi! My 14mm came a few days ago and I want to try prefocus with that lens for some street photo. I can't find any distance information (like in fuji X100) and of course the tiny pancake doesn't have distance info in it. So I the only way is to focus at an object and than switch to MF. It's too slow if we apply this on street. I know we can always rely on E-P3 blazing AF . But in low light + built in flash, MF+pre focus is needed too. Do you have any suggestion? Thanks!
