"The new telephoto zoom from Tamron, designed exclusively for digital SLR cameras, is ideal for anyone who wants to capture truly dynamic telephoto images. It goes far beyond the capabilities of the standard zoom that comes with a digital SLR camera. Ideal for photos of family fun, sport events, scenery, and portraiture, the lens naturally creates a out-of-focus background that emphasizes the main subject of your photo.
