The Sigma 150-500mm f/5-6.3 APO DG HSM Lens is for Digital SLR cameras with a Nikon mount. It is an ultra-telephoto zoom lens ideal for nature, wildlife, or sports photography. This lens is designed for full-frame cameras and is also compatible with APS-C format DSLRs. The zoom range translates into the approximate focal length equivalence of 225-750mm when used with APS-C cameras.
A Hyper Sonic Motor (HSM) enables fast, smooth and quiet auto focus and its rear focus system prevents focus-dependent variation in aberration, provides quick, convenient manual focus and a non-rotating, non-extending front barrel during focus. Its APO apochromatic design with three Special Low Dispersion glass elements virtually eliminate chromatic aberrations and the DG-system and Super Multi-Layer coated optics reduce flare and ghosting.
For such a long telephoto zoom lens, this is a compact and lightweight option with an included rotating tripod collar. It is compatible with the optional Sigma APO teleconverter.
