This is a lightlly used Tamron SP AF 17-50mm f/2.8 XR Di-II LD ASP (IF) lens. Including original box with one cut out. This was used a few times, but well cared for, so it is like new. Includes hood. Originally purchased May 2007.
There is a nice review of this lens by Bob Atkins at:http://www.bobatkins.com/photography/revie...-50_review.html
He says: "The Tamron SP AF17-50mm F/2.8 XR Di-II LD Aspherical [IF] is a good lens. It's pretty sharp at all focal lengths, even wide open, but contrast does go up a notch when stopped down from f2.8 to f4. Chromatic aberration and distortion are generally well controlled, though there is noticeable barrel distortion at the wide end of the zoom range."
"If you're after high optical quality, a fast lens which can blur backgrounds and stop action but you don't want to spend more than about $500, the Tamron SP AF17-50mm F/2.8 XR Di-II LD Aspherical [IF] is a lens you could be very happy with."
