The Sigma 50mm F2 DG Contemporary Lens in Black for L Mount is a full-frame compatible lens that offers new value to mirrorless systems. The combination of superb optical performance with a level of compactness that is perfectly suited to smaller and lighter modern mirrorless cameras will bring you new opportunities for a perfect shot. The Sigma 50mm F2 DG Contemporary boasts exceptional optical performance with ultra-high resolving power to match the latest high-resolution mirrorless cameras. The AF drive system incorporates a quiet, high-speed stepping motor, making it suitable for still images as well as video recording.

Optical Correction Functionality

The lens also utilizes the camera's optical correction functionality, which is an advantage of mirrorless systems, Sigma's optical designers concentrated on correcting aberrations that can only be corrected by the optical design, thereby improving rendering performance and reducing the size and weight of the lens.

Multiple High-Precision Aspherical Glass Molded Lenses

The surface of molds for glass molding, which is a process that forms optical components by pressing glass materials at high temperatures, requires ultra-high precision. Sigma uses high-precision molds whose surfaces are controlled with an accuracy of plus and minus 5 nanometers (0.000005 mm) or smaller. High-precision aspherical glass molded lenses archive both good aberration correction and compact lens size.

Inner Focus System

To increase stability, this lens configuration uses movable internal lens elements that adjust focus without changing the length of the lens barrel.

Super Multi-Layer Coating

Super Multi-Layer Coating suppresses flare and ghosting by preventing reflections within the lens. In digital cameras, flare, and ghosting may also be caused by reflections between the image sensor and lens surfaces. Multi-layer coating is highly effective, assuring images of outstanding contrast.

Exceptional Build Quality with a Compact Form-Factor

It has an all-metal construction. The precision-cut aluminum parts not only give the barrel a sleek, stylish finish but provide superb durability that improves the quality of the entire product. Metal materials are also used in internal structures that slide with the operation ring for added robustness.

Magnetic Metal Lens Cap

The lens is accompanied by a dedicated magnetic metal lens cap, in addition to a normal plastic cap. This dedicated metal cap clips to the front surface of the lens magnetically. It is no exaggeration to say that this meticulously crafted cap represents the finishing touch to the lens.
