Debating getting the Olympus 45/1.8, I already sent one private message to a seller on here (but no response yet). Basically debating if I should just go ahead and get it new since they're going for about 350 new. Currently I only have three autofocus lens in my setup: Olympus 17/2.8 Sigma 30/2.8 Sigma 60/2.8 And the rest are manual focus Olympus 9mm f/8 Pentax-M 50mm f/1.4 Tamron SP 90mm f/2.8 1:1 Jupiter-11 135mm f/4 I like my adapted Pentax M, especially when using the tilt adapter but sometimes I just want it a little lighter/smaller and sharper at it's widest aperture (f/2 is decent, f/1.4 is just 'soft', almost halo-like). The 45/1.8 seems like it could do the trick and would make my AF selection 17/2.8 -> 30/2.8 -> 45/1.7 -> 60/2.8. Unless you can think of another lens, similarly priced (400 or less), that's fast (f/2.0 or faster), that might fill a void somewhere in there.
