Camera House Sigma 40mm f/1.4 DG HSM Art Series Lens - Canon
The technical details behind this lens Sigma 40mm f/1.4 DG HSM Art Series Lens - Canon features an impressive bright f/1.4 maximum aperture that is well-suited for working in low-light conditions and also offers greater control over the focus position when using shallow depth of field techniques. 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. A Super Multi-Layer Coating is featured and helps to minimize flare and ghosting for greater contrast and color accuracy when working in strong lighting conditions. The lens sports a Hyper Sonic Motor to produce quick, smooth, and quiet autofocus performance with full-time manual focus override. The physical design features a brass bayonet mount, which offers rigidity and mounting precision along with a seal to guard against dust and moisture. A rounded nine-blade diaphragm contributes to a pleasing bokeh quality. This lens is designed to achieve truly notable optical performance and is ideally suited for creative and artistic applications. Short-normal prime is designed for full-frame Canon EF-mount cameras, however is also suitable for APS-C models where it provides a 64mm equivalent focal length. This lens is compatible with the optional Sigma USB Dock for fine-tuning different lens characteristics and updating its firmware. Great Optical Design A Super Multi-Layer Coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and color-neutral imagery, even in backlit conditions. Impressively bright f/1.4 maximum aperture is well-suited for working in low-light conditions and also provides greater control over the focus position when using shallow depth of field techniques. The three F Low Dispersion (FLD) and three Special Low Dispersion (SLD) elements are featured in the optical design and help to reduce color fringing and chromatic aberrations for improved clarity and color accuracy. One aspherical element is used to help limit distortion and spherical aberrations and also contributes to greater overall sharpness and accurate rendering. The rounded nine-blade diaphragm contributes to a smooth and pleasing bokeh quality. Outstanding Features The integrated HSM (Hyper Sonic Motor) realizes quick and quiet autofocusing, which is further complemented by an optimized AF algorithm to produce smoother focusing performance. The HSM also permits full-time manual focus control simply by rotating the focus ring at any time. A specialized electromagnetic aperture mechanism provides greater exposure control stability that is especially beneficial when working with fast continuous shooting rates. The bayonet mount is constructed from brass for ensured accuracy and durability. A rubber sealing is incorporated in the mount design to render it dust- and splash-resistant. Protective coating has been applied to the front element and is both water and oil-repellent to aid in cleaning.
