As a versatile alternative to fixed lenses, the Sigma 150-600mm lens is a great option for photographers looking for dynamic range in focal length. Joining the Global Vision lineup, the 150-600mm f/5-6.3 DG OS HSM Contemporary Lens from Sigma is designed for Canon EF-mount cameras and brings versatile super telephoto zoom focal lengths in a compact, weather-resistant package. The full frame lens features an aperture range from f/5-6.3 to f/22 and utilizes one FLD and three SLD elements. Also, this lens features a Hyper Sonic Motor for fast, quiet autofocus and has an Optical Stabilizer with an accelerometer for improved panning performance. Our Londolozi Rangers and photography staff enjoy using this lens for a myriad of different subjects, and we think you will to.
