High-performance optics

The 105mm F1.4 DG HSM | Art boasts outstanding optical quality, with excellent rendering of detail right into the corners even wide open at F1.4.

The lens has an advanced optical design made up of 17 elements in 12 groups, including 1 aspherical element, 2 SLD elements and 3 FLD elements. This ensures razor-sharp results with very minimal chromatic aberration, flare, distortion and vignetting.

An advanced Super Multi-Layer Coating helps to reduce flare and ghosting when working in bright direct sunlight.

High contrast results

Thanks to its superb control of flare and ghosting, which keeps image saturation and contrast high, the 105mm F1.4 delivers punchy results with strong blacks.

High-precision construction

The superb build quality of the 105mm F1.4 DG HSM is exactly as you’d expect from an Art-line lens, both in its intuitive ergonomics and in the quality of craftsmanship.

The lens’ outer barrel is made of a polycarbonate called Thermally Stable Composite (TSC), which is not only strong and light, but has a similar thermal expansion rate to aluminium. This ensures that the interior aluminium parts and the exterior TSC parts behave in the same way as temperatures change.

The focus ring is rubberised for easier operation, and focusing is internal, meaning the lens never changes length.

The lens has a tripod foot (TS-111) with an Acra Swiss dovetail foot so that it can be attached to most tripod heads without the need for a plate. The collar can be removed for easier hand-holding.

To reduce flare and ghosting in bright sunlight, and to help protect the front element from damage if dropped, the lens has a robust lens hood. This includes a rubberised ring for easier removal and fitting.

The durable brass mount is surrounded by a rubber seal to help keep out dust and moisture.

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.
