The Sigma 90mm F2.8 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 90mm F2.8 DG Lens 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.

SLD Glass Elements

The lens is built using the very latest optical technology and includes five SLD glass elements. This helps to reduce axial chromatic aberration that cannot be corrected in-camera, allowing the lens to achieve high resolution and clear image quality with no color bleeding. A high-precision glass molded aspherical lens provides both high resolution and beautiful bokeh. Photographers can enjoy shooting with soft, large bokeh without coloration and this is something that only a full-frame lens is able to deliver.

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.

Focuses on Fine Details

With a minimum focusing distance of 50cm and a maximum magnification ratio of 1:5, close-up macro-style photography is possible. The lens highlights the subject, allowing photographers to focus on fine details or create more abstract compositions.

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.

Focus Movement

A focus movement method of mirrorless lenses for mirrorless cameras in relation to the rotational angle of the focus ring during manual focusing. With 'non-linear focus' the amount of focal point movement varies depending on the focus ring rotational speed. With linear focus, if the focus ring rotational angle is the same, the amount of focal point movement remains the same regardless of the focus ring rotational speed.

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.
