Being part of the Art line within Sigma's Global Vision series, this lens is designed to achieve remarkable optical performance and is perfectly suited for artistic and creative applications. Sigma 40mm f/1.4 DG HSM Art Series Lens - Leica L-Mount offers great optical performance and reliable design. Super Multi-Layer Coating is offered and helps to minimize flare and ghosting for greater contrast and colour accuracy when working in strong lighting conditions. It features a fast f/1.4 maximum aperture that helps to achieve shallow depth of field and selective focus effects, and suits working in challenging lighting conditions. The optical design incorporates a series of low dispersion and aspherical elements, which help to improve sharpness and clarity by controlling both spherical and chromatic aberrations. The rounded nine-blade diaphragm contributes to a smooth and pleasing bokeh quality. The specialized electromagnetic aperture mechanism provides greater exposure control stability that is especially beneficial when working with fast continuous shooting rates. The integrated Hyper Sonic Motor (HSM) realizes quick and quiet autofocusing, which is further complemented by an optimized AF algorithm to produce smoother focusing performance. The HSM allows full-time manual focus control simply by rotating the focus ring at any given moment.
