Capture expansive landscapes in remarkable detail
Bring the night sky to life like never before with the SIGMA 14mm F1.4 DG DN | Art, the world’s first 14mm F1.4 aperture lens for mirrorless cameras*. The lens has been designed from the ground up for wide-angle applications such as astrophotography, landscapes, weddings and interiors, and is available in L-Mount and Sony E-mount. Thanks to advanced chromatic aberration and coma flare control the lens delivers exceptionally impressive edge-to-edge performance across all apertures, even when shooting very challenging subjects such as the night sky.

The world’s first full-frame 14mm lens with an F1.4 aperture
The SIGMA 14mm F1.4 DG DN | Art is the world’s first F1.4 mirrorless lens with an angle-of-view this wide. The F1.4 aperture is two thirds of a stop brighter than its predecessor the SIGMA 14mm F1.8 DG HSM | Art for DSLRs, which means it allows 58% more light on to the camera’s sensor. This makes it even better suited to photographing the night sky, as well as for using hand-held in dark environments.
Optimised for landscapes and astrophotography
With its advanced optical design that includes 1 SLD, 3 FLD and 4 aspherical elements, the lens has been designed with landscapes and 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’s sophisticated optical design. Using optical aberration control selectively in this way helps to keep the size and weight of the lens down.
Lens heater retainer
At the front of the barrel is a Lens Heater Retainer, which was a feature introduced on the SIGMA 20mm F1.4 DG DN | Art. 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.
MFL and AFL buttons
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. An AFL button is also included. It can be customised depending on the camera and system.
Fast and accurate focusing with the HLA motor
The SIGMA 14mm F1.4 DG DN | Art utilises SIGMA’s own HLA (High-response Linear Actuator) motor. It is able to focus quickly on subjects and remains quiet thanks to the motor’s linear design. The HLA Motor is compatible with focus tracking and burst shooting modes on compatible cameras.
Brand-new specially designed lens cap
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. Previous lenses such as the SIGMA 14mm F1.8 DG HSM | Art used a push fit type cap. The new front cap now features a secure lock mechanism to prevent the cap from falling off unintentionally.

Essentials
You'll find our philosophy and craftsmanship in every product
Our lens line-up fully expresses our approach to lenses and photography itself. All of our lenses belong to one of three lines—Contemporary, Art or Sports—all of which share our development philosophy and advanced manufacturing system. High performance, high quality and high end in every respect, these lenses give people who love photography lasting value and consistent, exciting results. The secret is our passion for craftsmanship that we put into every production process and every product.
Evaluation with Sigma's own MTF measuring system “A1”
We used to measure lens performance with MTF measuring system using conventional sensors. However, we’ve now developed our own proprietary MTF (modulation transfer function) measuring system (A1) using 46-megapixel Foveon direct image sensors. Even previously undetectable high-frequency details are now within the scope of our quality control inspections.
