Well the lens arrived today from keh, and I got to check it out before. It's very clean looking besides a bit of dust which I cleaned out from inside, but slow speeds are off, 1 sec is closer to 2, and 1/2 is about 1. I wished for a pc flash sync port, but unfortunately its a bi post which I'll have to get an adapter for. The whole setup does close up very nicely into my wista sp body! And the cells are just tiny and don't really protrude out or into the body much at all. I won't get a chance to shoot with it until the weekend though, hopefully it performs!
