Quantaray 28-80mm f3.5-5.6

     This particular lens was made by Sigma for Ritz Camera in the 90's.  It was a basic kit lens, but as you can see it performs well.  My copy has a Nikon F 'D' mount.  It is a chore to focus on my T2i because these lenses aren't dampened for manual focus.  It is reasonably sharp at 28mm wide open.  It is soft at 80mm wide open but tightens up quickly at f8.  Color rendition is accurate, but color saturation is a bit low.  Fringing is barely noticeable.  This lens frequently sells for less than $20.  Honestly, I don't know why.  It's a good lens.  It performs better than name brand kit lenses of the same era and is made better, too.
