Has anyone ever used the new minolta 28-75mm F2.8 that came out around the time of hte Maxxum 7D? I havn't seen any reviews for this piece. As far as I can tell from Minolta's lens chart, it will function on any maxxum/dynax AF mount body. Is this true? For $400ish, I wouldn't except a lens with a f2.8 to be great....but at the same time, $400ish for a f2.8 is a pretty good deal. Might be a nice walk around except it looks kinda plasticy (and the focus scale looks wierd). Does anyone have any feedback or samples from this lens?
