This Sigma 50-500mm f/4.5-6.3 DG HSM APO Lens for Sigma is for digital SLR cameras with a Sony lens mount. The lens has a standard to ultra telephoto zoom range that is ideal for nature, wildlife, or sports photography. The range translates into an equivalent 75-750mm when used with digital SLR cameras with an APS size chip. The lens is also compatible with full frame cameras. You can even increase your telephoto range by using the Sigma APO teleconverters.
The OS (Optical Stabilizer) system minimizes image blur caused by camera shake, and offers the equivalent of shooting at a shutter speed 3-4 stops faster. This allows handheld telephoto zoom shooting even in poorly lit conditions.
The use of the OS (Optical Stabilizer) system, HSM (Hyper Sonic Motor), APO apochromatic design, four elements of SLD (Special Low Dispersion) glass, and multicoated optics all enable this lens to provide a high level of performance throughout its entire zoom range. A rear focus system ensures quick, convenient manual focus and a non-rotating front barrel.
The improved DG lens design corrects for various aberrations. This lens is specially coated to get the best color balance, while cutting down on ghosting caused by reflections from the digital image sensor. The lens provides the utmost correction against lateral chromatic aberration, which is a serious problem for digital SLR cameras.
Note! If the camera body does not support the HSM motor, auto focus will not work.
