NEW 28-105mm 2.8 AF ZOOM LENS FOR MINOLTA MAXXUM SONY - eBay (item 220458098679 end time Aug-25-09 10:19:51 PDT) I haven't been able to find out much about this brand, nor any opinions of people who have used a Cosina product. Does anyone have any feedback? I've been scoping out lenses for a while, and the price just seems too good to be true. I've sent a couple of emails to the seller, and they have promised that if I wasn't happy with the product that they'd be more than happy to refund my money and shipping. Opinions?
