Sigma 14mm F1.4 DG DN Art Lens - Sony E-mount

The Sigma 14mm F1.4 DG DN Art is a full-frame Lens that has been designed for wide-angle applications such as astrophotography, landscapes, weddings and interiors. Thanks to advanced chromatic aberration and coma flare control the lens delivers exceptionally impressive edge-to-edge performance across all apertures, even when shooting the night sky. The lens has an advanced feature-set including an aperture ring with both lock and de-click functions, a customisable AFL button, a Manual Focus Lock switch, a rear filter holder, and a built-in Lens Heater Retainer to hold a heat strip firmly in place.
There’s also a newly redesigned front cap that securely locks onto the lens and features two compartments for storing sheet-type rear filters. With its ultrabright aperture and ultra-wide focal length this innovative and unique optic opens up a world of creative possibilities for nightscape, landscape, cityscapes and interior photographers.

Optically optimised for astrophotography
With its advanced optical design that includes 1 SLD, 3 FLD and 4 aspherical elements, the lens has been designed with astrophotography in mind. With a particular emphasis on optical quality at infinity focus, the lens has very well-controlled optical aberrations and sagittal coma flare, which ensures that bright points of light remain pin-sharp and round at all apertures and across the entire frame.

The lens uses in-camera optical aberration control profiles to help correct for any distortion or vignetting, whereas optical issues that are more difficult to improve digitally, such as corner softness and chromatic aberration, are eliminated by the lens' sophisticated optical design. Using optical aberration control selectively in this way helps to keep the size and weight of the lens down .

Fast, smooth AF
This lens is is fitted with Sigma’s new High-response Linear Actuator (HLA) motor, which delivers faster, smoother, quieter and more accurate focusing than a stepping motor. This is only the third Sigma lens to be designed with this technology, ensuring very responsive focusing in all shooting situations.

Professional feature set
The 14mm F1.4 DG DN | Art has a professional feature-set that makes it easier for photographers and film makers to achieve the best possible results. Built in to the barrel is an aperture ring, which can be set to auto for aperture control on the camera. With a very precise action, the ring can also be de-clicked if preferred, or locked in place so that it’s not accidentally knocked.

Superb build
At the front of the barrel is a Lens Heater Retainer. This helps hold a heat strip in place, which are often used by astrophotographers when shooting in cold conditions to prevent condensation build-up on the front element.

Rear filter holder
The lens features a rear filter holder that allows sheet-type filters to be attached. Soft type filters are preferred by astrophotographers as they make stars appear softer, larger and brighter. Other types of sheet-type filter can also be used.

A brand-new front lens cap has been specially designed with these types of filters in mind. Two filter slots are provided to store pre-cut sheet-type filters, allowing them to be carried with the SIGMA 14mm F1.4 DG DN Art lens at all times. The new front cap now features a secure lock mechanism to prevent the cap from falling off unintentionally.

TS-141 Tripod Socket included
An MFL (manual focus lock) switch can be found on the side of the lens barrel. This allows astrophotographers to find infinity then switch the MFL switch to Lock, which completely disables the focus ring. This means that even if the ring is knocked the focus will remain at infinity. As this type of ultra-wide-aperture lens is by nature relatively heavy, attaching the camera to a tripod using the camera’s tripod thread can make the set-up front-heavy, putting the thread under stain and making the camera unstable. So included with this lens is the TS-141 Tripod Socket, which ensures a more balanced set-up closer to the centre of gravity when mounted on a tripod.
