The Sigma 50-500mm f/4.5-6.3 APO DG OS HSM for Sony A Mount is an exceptionally versatile normal length all the way to super-telephoto length lens that features an Optical Stabilizer system to keep your images sharper even when shooting at low shutter speeds. It also has a fast and quiet Hyper Sonic Motor and apochromatic optics for better correction of chromatic and spherical aberration than the much more common achromat lenses. The focal length is perfect for shooting situations where you just don't know how much reach you're going to need and the 4.5 aperture is just barely fast enough for most lighting situations. This lens is suitable for arena events, sports, ceremonies, and wildlife shooting.
This lens is compatible with full frame and crop frame sensor A mount cameras.
