Sigma 15mm F1.4 DG DN Diagonal Fisheye | Art Lens Features In Detail

Bright f/1.4 Aperture for Low Light Shooting

The incredibly fast f/1.4 maximum aperture gives photographers immense creative control. By allowing more light into the camera, you can easily shoot handheld in low-light situations with faster shutter speeds. This reduces image noise at high ISOs. The shallow depth of field from f/1.4 also isolates subjects with a creamy smooth background blur. Whether you’re shooting events, night skies or environmental portraits, this lens delivers beautiful f/1.4 images.

180° Angle of View for Immersive Perspectives

Fit expansive scenes into every image with the extreme 180-degree angle of view, which delivers massively exaggerated perspectives. This unique full-frame fisheye view allows very close working distances for unique distortions of subjects and intense environmental contextualisation. Interior, architecture and landscape photos take on an immersive look. Portraits get wrapped into the environment. The ultra-wide field of view also permits stunning star trail images across the entire sky.

Advanced Optics for Edge-to-Edge Sharpness

Meticulous lens design with special low dispersion and aspherical elements achieves impressive sharpness and clarity across the whole frame. With 21 elements in 15 groups, optical aberrations are effectively controlled so stars appear pin-sharp even at f/1.4. The advanced optics excel with today’s high-resolution cameras, providing detailed images from edge to edge.

Weather-Sealed Metal Construction

The lens features dust and splash-proof sealing at key junctures, letting you shoot in challenging environments worry-free. Designed with a metal construction, it has the durability for active outdoor photography excursions and long shoots into the night. The metal also gives it a refined look and feel. Paired with a similarly weather-sealed L-mount or Sony mirrorless body, you’ll be ready for whatever nature can throw at you.

Built-In Rear Filter Holder

Creative astrophotographers will love the sheet filter holder built into the barrel close to the lens mount. Simply slide gelatin filters into the holder to make colourful starscape images or soft-focus dreamy stars. It even comes with an innovative locking lens cap with slots to store spare pre-cut filters for convenience. Videographers can also use colour filters to set moods.

Innovative Lens Heater Retainer Band

To prevent condensation from forming on the lens elements in cold conditions, astrophotographers will often wrap a heat strip around the front of lenses. However, these can easily slip off. Sigma has invented a handy lens heater retainer band that snugly holds the heat strip firmly in place while shooting stars all night.

Fast and Quiet Autofocus

Thanks to the High-Speed Linear Actuator (HLA) focus motor, autofocus is extremely fast, smooth and near silent. Shooters can precisely track subjects with reliable speed or do quick AF checks in video without noise. Manual focus benefits from non-linear focus ring characteristics for fine adjustments.
