Selling two great Nikon lenses. A Tamron, 28-105 mm lens, with a constant f/2.8 aperture. Tamron doesn't make this lens anymore, and Nikon doesn't offer anything in that focal length range with a constant f/2.8 aperture. Works on both film and digital bodies. Purchased new for $800, asking for $550. Comes with a UV filter.

Also selling a Sigma 70-200 mm zoom lens, Nikon mount, with a constant f/2.8 aperture. This comes with a 2x teleconverter. If used on a digital body, this gives you a 600 mm lens at f/5.6, which is phenomenal for this price range. Works on film and digital bodies. As a set, would sell for over $900 on ebay.
