I've got an epm1 and have been shooting solely with manual lenses. Mostly the 50mm super tak. I love the character from this lens, but a friend asked me to shoot her son's fifth birthday party and out of 80 photos only 40 up to standard. So I am in the market for an autofocus lens. I've seen plenty of photos from epm1s with the pl25 and the oly45 but I haven't seen any with the 75mm. I am quite interested in the lens, but the high price tag makes me weary. I know what it is capable of, but would it be worth having it on my camera?
