Ideal for wildlife, sports, landscapes, motorsports, and countless other photographic endeavors, the Sony E-mount 150-600mm f/5-6.3 DG DN OS Sports Lens from Sigma offers the features and image quality that professionals demand. This lens provides high rendering throughout the entire zoom range at all apertures, and ghosting, flare, and various types of aberrations are all well controlled. An updated and redesigned autofocus system offers both speed and precision by incorporating an AF actuator driven by a stepping motor, as well as a high-precision magnetic sensor. Optical image stabilization delivers approximately four stops of compensation, with two standard OS modes for both handheld shooting and panning situations. A new Zoom Torque switch gives users the option to adjust the level of zoom ring resistance from Lock (locked at the wide end for transport), Tight (prevents zoom creep), and Smooth (for easy, smooth zooming). Additional on-lens controls include a Focus Limiter switch, OS Mode switch, Custom switch for custom OS settings, and three customizable AFL buttons. As part of the Sigma Global Vision Sports line of lenses, the 150-600mm f/5-6.3 DG DN OS Sports Lens is specifically designed for everyday use in challenging conditions. A dust and splash resistant structure protects the lens against water and dust intrusion, and a water and oil repellant coating on the front element resists moisture and fingerprints. Barrel construction consists of aluminum and TSC (Thermally Stable Composite) for an ideal combination of toughness and improved portability. Additionally, a magnesium tripod socket with a removable Arca-type foot and 90° click stops provides a sturdy support option.
