Sigma 500mm f5.6 DG DN OS Sport Lens – L-Mount

hand-held shooting. The built-in HLA (High-response Linear Actuator) motor delivers fast, smooth, accurate and nearsilent autofocus, ensuring that the subject remain sharp, even when using subject tracking modes. The built-in OS provides 5 stops of effective stabilisation thanks to SIGMA’s proprietary OS2 algorithm.

Small size, big results

To reduce the size of the lens without compromising optical quality, the lens uses convex low-dispersion elements towards the front of the lens barell. The design of these glass elements also keeps chromatic and axial aberrations to a minimum. Flare and ghosting are prevented by refractive lenses, ideal for when shooting in backlit environments such as sporting arenas or when strong light sources are in or close to being in frame.

When compared to the SIGMA 500mm F4 DG OS HSM | Sports for DSLRs, the lens impressively small and a whole lot lighter, all achieved without using conventional diffractive optical elements.

Advanced AF and stabilisation

The SIGMA 500mm F5.6 DG DN OS | Sports is perfectly suited to fast-paced action such as birds in flight or high-performance cars on a race circuit. Its HLA motor delivers extremely fast, accurate and near-silent AF that far outperforms traditional stepping motors. Low-light environments such as concerts and floodlit pitches are no trouble thanks to the exclusive OS2 algorithm, providing an effective 5 stops of stabilisation. The lens also features two OS modes. Mode 1 can be used for all types of photography to help reduce unwanted camera shake at slower shutter speeds. Mode 2 employs SIGMA’s Intelligent OS algorithm for smoother panning shots – ideal for tracking a fast-paced object as it moves. Regardless of the orientation of the lens, the stabilisation is effective for both vertical and diagonal movement and doesn’t interfere with the panning motion.
