Sigma 14mm F1.8 DG HSM Art lens for Canon EOS

A wide Art prime with an F1.8 aperture, makes this lens one of the most useful on the market for wide-angle astrophotography and nightscapes.

Its F1.8 aperture allows the camera to gather an exceptional amount of light (twice the amount of light as an F2.8 lens), meaning a huge amount of star detail can be recorded at acceptable ISO settings without star trails forming.

With its outstanding optical quality, the lens is also perfect for landscapes, interiors and architecture, and owing to its wide aperture it can be used for full-body environmental portraits with a shallow depth-of-field.

• Aperture Range: f/1.8 to f/16
• Three FLD Elements, Four SLD Elements
• Four Aspherical Elements
• Super Multi-Layer Coating
• Hyper Sonic AF Motor, Manual Override
• Rounded 9-Blade Diaphragm
• TSC Material, Brass Bayonet Mount

The 14mm F1.8 boasts a very advanced optical design with no fewer than 3 FLD elements, 3 SLD elements and 4 aspherical elements, which helps to eliminate coma flare, chromatic aberration and ghosting.

A perfect astro lens

As well as being a very capable landscape lens, the 14mm is ideal for astrophotography, given its ultra-wide aperture of F1.8. This allows it to collect four times as much light as an F2.8 lens, revealing a huge amount of star detail at relatively low ISOs in exposure times short enough to eliminate star trails.

High-performance optics

The 14mm F1.8 DG HSM | Art for DSLRs boasts outstanding optical quality, with excellent rendering of detail right into the corners, and superb peripheral brightness, even wide open at F1.8.

The lens has an advanced optical design made up of 16 elements in 11 groups, including 4 aspherical elements, 4 SLD elements and 3 FLD elements. This design ensures razor-sharp results with very minimal transverse chromatic aberration, flare, distortion and vignetting.

An advanced Super Multi-Layer Coating helps to reduce flare and ghosting when working in bright direct sunlight, which is particularly important on an ultra-wide-angle optic.

High-precision construction

The superb build quality of the 14mm F1.8 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 a uniform way as temperatures change.

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

To reduce flare and ghosting in bright sunlight the lens has a robust petal-type lens hood, and also Super Multi Layer Coating on the surface of the glass elements.

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.
