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 lens has an advanced feature-set including an aperture ring with both lock and de-click functions, a customizable 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, cityscape and interior photographers.

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.

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’s sophisticated optical design. Using optical aberration control selectively in this way helps to keep the size and weight of the lens down.

Understanding: Aperture

Aperture is the opening in a camera lens that controls how much light enters the camera. It's measured in f-stops like f/2.8 or f/8. Lower f-stop numbers mean wider openings, letting in more light and creating a shallow depth of field (blurry background). Higher f-stop numbers mean smaller openings, letting in less light and creating a larger depth of field (more of the scene in focus). Aperture also affects the quality of out-of-focus areas in the image (bokeh).

Understanding: Lens Types

Different lenses have different purposes to achieve different styles of images, some popular ones include:
Prime Lens: Fixed focal length, sharp images, great for portraits and dark settings.
Zoom Lens: Variable focal length, versatile for different shots and everyday use..
Wide-Angle Lens: Captures wide scenes like landscapes.
Telephoto Lens: Magnifies distant subjects, ideal for sports & wildlife.
Macro Lens: Perfect for close-up photography of small subjects.
Fisheye Lens: Ultra-wide perspective, creates unique images.

Understanding: Lens Mounts

Different camera brands use different lens mounts, which are like connectors that attach lenses to camera bodies. Each mount is specific to a particular brand and camera series. For example, Canon uses the EF and RF mounts, Nikon uses the F mount, Sony uses the E mount for its mirrorless cameras. These mounts dictate which lenses are compatible with which cameras. Some brands offer adapters to use lenses from other systems, but it's essential to ensure compatibility for proper functionality and autofocus performance.

Understanding: Manual and Autofocus

Manual focus and autofocus are two ways to adjust the sharpness of a camera lens. With manual focus, you turn a ring on the lens to bring the subject into focus yourself, giving you full control over what appears sharp in the image. Autofocus, on the other hand, relies on the camera's built-in technology to automatically adjust the focus for you, usually by detecting contrast or phase differences in the scene. Autofocus can be convenient, especially for fast-moving subjects or when you need to capture a quick shot, whereas manual focus allows for precise adjustments and creative control over the final image.
