Sigma AF 90mm F2.8 DG I C lens for L-Mount, Silver 

Part of Sigma’s I series range of lenses for full-frame mirrorless cameras, the 90mm F2.8 is a premium compact prime that combines uncompromising image quality, outstanding build quality and a portable form factor.

The lens sports a wide F2.8 aperture, which allows photographers to achieve a shallow depth-of-field and blur-free, hand-held images in low light. The 90mm focal length is perfect for portraits, and is also ideal for travel, street, wedding and family photography, as well as video.

As with Sigma’s other I series lenses, the 90mm F2.8 has a sleek all-metal body with retro styling, and includes a metal focus ring, a metal aperture ring, a metal lens hood, and even a metal lens cap that attaches to the lens magnetically. The lens is essentially designed for photographers and film-makers who value the experience of taking a picture just as much as the quality of the final result.

At less than 300g, the SIGMA 90mm F2.8 is portable enough to be carried around for casual day-to-day shooting, but thanks to its outstanding optics, fast AF and impressive build, it’s equally well-suited to heavy professional use.

It's incredible that a full-frame lens with such exceptional optical performance and build quality can weight in at less than 300g.

Perfect for Portraits

The 90mm focal length is around the preferred focal length for portraits, because it is generally considered to give the most flattering perspective on the face when standing at the correct distance for a head-and-shoulders composition. The F2.8 aperture delivers a shallow depth-of-field for blurry backgrounds, and the bokeh is smooth and attractive.

Excellent Build Quality

As with the other optics in the I series range of premium compact primes, the 90mm F2.8 has an all-metal build using precision-cut aluminium parts. Its robust construction and ultra-portable design make it perfect for street, travel, wedding and portrait photography. The lens has a rubber seal around the mount to keep out dust and moisture.

An aperture ring is built in so that users can change aperture using the lens or the camera.

The tactile knurled metal finish used for the lens hood, focus ring and aperture ring make handling the lens and changing settings extremely intuitive. Included with the lens is a magnetic metal lens cap in addition to the regular plastic cap, which further improves ease of use.

• Metal mount with seal: Protects against dust and moisture.
• All-metal aperture ring: Allow aperture to be changed on the lens or the camera.
• All-metal focus ring: With smooth action for precise focusing.
• Ultra-compact body: Weighs only 225g, ideal for landscapes, street and travel.
• Petal-shaped hood: All-metal with individually machine knurled grooves.

High-Performance Optics

Despite being extremely small and light, the 90mm F2.8 does not compromise on optical quality. Its advanced optical design includes 11 elements in 10 groups, of which 1 is an aspherical element and 5 are made with SLD glass. These help keep the lens compact while greatly reducing the appearance of chromatic aberration around areas of high contrast.

Vignetting is very minimal even wide-open and chromatic aberration is very minimal even in very high contrast areas.

A special Super Multi-Layer coating on the elements helps reduce flare and ghosting for rich, high-contrast results.

Magnetic Lens Cap Holder

Available as a separate accessory, Sigma’s innovative magnetic lens cap holder can be clipped to clothing or a bag to securely hold any I series magnetic lens cap. This helps keep the cap safe while the camera is in use.

Sigma I Series Range

The lens is part of the I series range of primes, which sit in the Contemporary line-up. They are designed to offer mirrorless photographers outstanding optical quality and premium usability in a compact package.

With similar optical character and the same sleek external design, the lenses are ideally used as a set, ensuring consistent bokeh, colour rendition, optical precision and usability.

Made in Japan

All Sigma cameras and lenses are designed, manufactured and assembled at their sole factory at Aizu in Japan. This domestic production model is unusual in today’s industry, with most imaging companies opting to outsource to other countries to reduce costs. But SIGMA believes that keeping virtually all manufacturing, processing and assembly in Aizu is essential for creating innovative, carefully thought-out and impeccably constructed products that meet the high standards demanded by professional photographers and film-makers around the world.
