Sigma AF 45mm F2.8 DG I C lens for L-Mount, Silver 

For photographers needing an ultra-portable fast-aperture standard prime for day-to-day use, the SIGMA 45mm F2.8 is about as compact as it gets.

Edge-to-Edge Sharpness in a Compact Body

This full-frame standard prime designed specifically for mirrorless systems was the first in Sigma’s I series line of lenses, and is designed as a portable day-to-day optic that balances perfectly on a modern mirrorless body. It can be used for a wide range of photographic applications, including portrait, street, wedding and travel photography, as well as general day-to-day shooting.

Exceptional Build Quality

As with the other optics in the I series range of premium compact primes, the 45mm F2.8 has an all-metal build comprising precision-cut aluminium parts. Its robust construction and ultra-portable design make it perfect for street, travel and wedding photography, and the ideal lens for general day-to-day shooting. The lens has a rubber seal around the mount to keep out dust and moisture.

An aperture ring allows photographers to change aperture on the lens, or in Auto mode, on the camera if preferred.

The tactile knurled metal finish used for the lens hood, focus ring and aperture ring make handling the lens and changing settings extremely intuitive.

• Metal mount with seal: Protects against dust and moisture.
• All-metal construction: Including metal aperture and focus rings.
• Metal lens hood: Beautifully crafted individually-machine knurled grooves.
• Ultra-compact body: Weighs only 215g, ideal for street, travel and day-to-day shooting.

High-Performance Optics

Despite being extremely compact, the 45mm F2.8 does not compromise on optical quality. Its advanced optical design includes 8 elements in 7 groups, of which 2 are aspherical elements.

These help keep the lens compact while greatly reducing the appearance of chromatic aberration around areas of high contrast. Results are razor-sharp across the whole frame even when working wide open.

Smooth Bokeh Effects

With its F2.8 aperture it possible to achieve a shallow depth-of-field for background fall-off. The bokeh is smooth and attractive and doesn’t distract from the in-focus subject.

The fast aperture is also useful in low light conditions, where the lens can be used hand-held with a reduced risk of camera-shake.

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.
