Sigma 14mm f/1.4 DG Art Lens for L Mount

Sigma 14mm f/1.4 DG Art Lens for L Mount Summary

The Sigma 14mm f/1.4 DG Art Lens for L Mount is a full-frame, ultra-wide-angle prime for photographers who expect the highest optical precision and reliability from their equipment. As the world’s fastest 14mm lens for mirrorless cameras, it combines an exceptionally bright f/1.4 aperture with advanced optical engineering and robust build quality, making it ideal for astrophotography, landscapes, interiors, architecture and creative wide-angle portraiture.

Sigma’s Art-series optical formula features 19 elements in 15 groups, including four aspherical, one SLD and three FLD elements to achieve consistent sharpness and excellent control over chromatic aberration across the entire frame. The inclusion of Sigma’s largest ever double-sided aspherical element plays a key role in suppressing sagittal coma flare and distortion, allowing stars and fine details to remain crisp even at wide apertures.

The lens offers refined control for both stills and video shooters, with a de-clickable aperture ring, customisable AFL button, AF/MF switch, and a lockable petal-shaped hood for reducing flare and protecting the large front element. A Manual Focus Lock switch prevents accidental focus movement during long exposures, while the rear filter holder accepts compact filters that fit securely behind the lens. There’s also a Heater Retainer for attaching anti-dew heaters, an essential tool when shooting in cold or humid environments. The brass L Mount is fully weather-sealed, and the outer barrel is constructed from Sigma’s Thermally Stable Composite, ensuring consistent handling and precision in varying temperatures.

With its advanced optics, meticulous construction and highly practical control layout, the Sigma 14mm f/1.4 DG Art Lens for L Mount offers professional and enthusiast photographers the same exceptional performance as the 20mm Art lens for the L Mount system.

Sigma 14mm f/1.4 DG Art Lens for L Mount in More Detail

Exceptional Optical Design

The Sigma 14mm f/1.4 DG Art lens features a sophisticated optical design with 19 elements in 15 groups, including four aspherical elements, three FLD and one SLD element. This provides excellent correction of chromatic aberration and sagittal coma flare, which helps to keep stars and point light sources round and defined even when shooting wide open at the fast f/1.4 aperture.

One of these aspherical elements is the largest double-sided aspherical glass lens ever used by Sigma, which plays a role in achieving superb sharpness across the entire frame, from corner to corner.

Coatings and Image Quality

Sigma’s Super Multi-Layer and Nano Porous Coatings reduce flare and ghosting when shooting towards bright light sources. The result is high-contrast images with accurate colour and rich tones, even in challenging lighting.

Additionally, an 11-blade rounded diaphragm produces smooth, circular bokeh, while ensuring subjects appear naturally against smooth defocused backgrounds.

Refined Handling and Controls

An aperture ring on the lens barrel can be clicked or de-clicked depending on shooting preference, with a lock switch to prevent accidental changes. The Manual Focus Lock switch ensures the focus ring remains fixed once set, which is particularly useful for astrophotography or long-exposure photography.

The internal focusing system keeps the lens length constant, which opens up the opportunity to shoot video with a gimbal or tripod. A customisable AFL button and an AF/MF switch provide access to essential controls during shooting, allowing the lens to be customised according to your needs.

Rear Filter Holder and Heater Retainer

Due to a curved front element, which is common for ultra wide lenses, the unit includes a rear filter holder for gel filters. This is positioned between the camera and lens to keep them protected from dust and scratches. A cutting template is included, allowing users to make their own custom filters from gel sheets.

A built-in Lens Heater Retainer is available to secure heating bands in place in order to prevent condensation during cold-weather photography and astrophotography, ensuring consistent optical clarity regardless of conditions.

Build Quality

The outer shell is constructed from a Thermally Stable Composite material that has been matched to the aluminium inner structure. This design ensures consistent performance even during shooting  in temperature changes.

A familiar durable brass mount with rubber sealing provides dust and moisture resistance, while the included lockable petal-type hood reduces flare, protects the front element and stays in place during transport.
