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. Additional on-lens controls include a Focus Limiter switch, an OS Mode switch, a Custom switch for custom OS settings, and three customizable AFL buttons. A cloud of 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. Updated optical design featuring 25 elements in 15 groups with 4 FLD and 2 ELD elements. Up to 4 stops of optical image stabilization correction with 2 selectable OS modes. High build quality with both aluminum and Thermally Stable Composite (TSC) components, contributing to its durability, lightness, and operational feel. Dual Action Zoom supports both zoom ring operation and pushes/pull zoom capability. Additional on lens-controls include an OS Mode switch, Custom switch, Focus Limiter, and 3 customizable AFL buttons.
