Sigma 70-300mm f/4-5.6 DL-M "Motorized" DG Macro Telephoto Zoom Lens with Built-in Motor Drive for Nikon SLR Cameras Including D40, D40X, & D60

For the price, it is a very good lens, in the hands of someone who knows how to use a lens of this focal length. In the 150-300 mm range, a solid tripod is a must, as is the case with ALL lenses of a longer focal length. While the auto focus is a bit clunky, I normally use it in the manual mode, as any auto focus lens can get confused when there is a large variation in the depth of field. I use the lens normally for flora and avian, though I have used it in landscape shooting to zoom in on a section of a cascade, and have obtained sharp results, especially in the f/8 setting. In short, it is a good addition to my arsenal, and would recommend it to anyone not looking to spend hundreds.Buy Sigma 70-300mm f/4-5.6 DL-M "Motorized" DG Macro Telephoto Zoom Lens with Built-in Motor Drive for Nikon SLR Cameras Including D40, D40X, & D60!
