Bundle - Sigma - 500mm f/5.6 DG DN OS Sports Lens - Included Value, Sony E

OS (Optical Stabilizer) functionSigma's OS (Optical Stabilizer) function uses sensors inside the lens to detect any motion, then moves specific lens elements in order to effectively minimize blur caused by such movement.OS2OS2 is the newly developed optical stabilizer algorithm. Compared to the previous algorithm used by Sigma lenses, OS2 improves the effect of optical stabilization significantly.Inner focus systemTo increase stability, this lens configuration uses movable internal lens elements that adjust focus without changing the length of the lens barrel.Compatible with Lens Aberration CorrectionMatching the optical characteristics of the lens, this function performs in-camera corrections of peripheral illumination, chromatic aberrations, distortion, and more, to further enhance image quality.HLA (High-response Linear Actuator)HLA is Sigma's proprietary linear motor. It drives the focus lens directly without going through gears or other mechanical parts, resulting in quiet, high-precision autofocusing.Super Multi-Layer CoatingSigma's own Super Multi-Layer Coating suppresses flare and ghosting by preventing reflections with in the lens. All lenses in the current Sigma range feature this original technology. In digital cameras, flare and ghosting may also be caused by reflections between the image sensor and lens surfaces. Here too, Sigma's Super Multi-Layer Coating is highly effective, assuring images of outstanding contrast.Water and oil repellent coatingIncorporates a water and oil-repellent coating that allows water to be wiped away easily and prevents oil and fat from sticking to the surface, even in challenging shooting conditions. At the same time, the maintenance of the lens surface becomes easier.Aperture ringAperture ring, designed to help users work intuitively.Aperture ring click switchOffers a de-click function for removing clicks by the aperture ring click switch, enabling seamless operations that are especially useful such as during video shooting.Aperture ring lock switchA ring lock system to prevent from unintended movement of the aperture ring during shooting.AFL buttonThe AFL button can be assigned with various functions widens the range of operations available on the lens.Focus Mode SwitchUsing this switch, it is possible to switch the focus mode between AF and MF.Dust and Splash Resistant StructureThis lens features a highly effective dust and splash resistant structure with special sealing at the mount connection, manual focus ring, zoom ring, and cover connection.
