A Fisheye Without Compromise
The SIGMA 15mm F1.4 DG DN DIAGONAL FISHEYE | Art takes the legendary fisheye perspective into a new class of optical performance. Combining an extraordinary 180° field of view with an ultra-fast F1.4 aperture and exceptional edge-to-edge resolution, it is designed for photographers who refuse to choose between expressive distortion and uncompromising detail.

World’s First Full-Frame F1.4 Diagonal Fisheye
This groundbreaking lens is the world’s first F1.4 diagonal fisheye interchangeable lens for full-frame cameras. Its powerful 180° perspective creates an unmistakable visual signature, opening spectacular possibilities for architecture, landscapes, interiors, creative portraiture and astrophotography.

180° of Extraordinary Perspective
The diagonal fisheye design fills the entire full-frame image with a dramatic 180° angle of view. Lines bend, spaces expand and subjects gain an almost surreal presence — giving photographers a perspective that conventional ultra-wide lenses simply cannot reproduce.

F1.4 for Astrophotography
The exceptionally bright F1.4 aperture makes this lens a formidable tool for starscapes and night photography. Advanced optical correction suppresses sagittal coma flare and other aberrations, allowing bright points such as stars to remain impressively well defined across the frame, even when shooting wide open.

21 Elements of Optical Precision
The optical construction consists of 21 elements in 15 groups, including four FLD elements, three SLD elements and two aspherical elements. This sophisticated architecture is engineered to control aberrations while maintaining outstanding resolution throughout the dramatic 180° field of view.

Art-Series Resolution Across the Frame
Sigma has subjected every lens to its proprietary MTF measurement system, ensuring exceptionally high optical standards. The result is a fisheye that delivers not merely a striking effect, but remarkable fine-detail reproduction across the entire image.

Built for Professional Control
The lens features high-speed autofocus, DMF and AF+MF support, an MF button and a VFL Manual Focus Lock switch. An aperture ring with a de-click function provides additional control for video production, while the lens heater retainer is especially valuable for astrophotography in cold conditions.

Professional Filter and Mounting Solutions
A dedicated rear filter holder supports gelatin filters, while the special locking front cap incorporates filter storage slots. The removable tripod socket adds stability and flexibility for carefully composed architectural, landscape and astrophotography setups.

11-Blade Rounded Aperture
The 11-blade rounded diaphragm contributes to smooth rendering when stopping down and helps create an attractive character in out-of-focus areas. Combined with the F1.4 aperture, it gives creators broad control over the visual mood of the image.

Built for the Field
The dust- and splash-resistant structure provides confidence during demanding outdoor work, while advanced optical design helps suppress flare and ghosting. The precision brass bayonet mount and robust professional construction reinforce the lens’s role as a serious creative instrument.

A Statement-Making Fisheye
At approximately 1,360 g and with a minimum focusing distance of 38.5 cm, the SIGMA 15mm F1.4 DG DN DIAGONAL FISHEYE | Art is unapologetically ambitious. It is a specialist lens created to turn extreme perspective into an unmistakable visual language — with the resolution, brightness and control worthy of the Art name.
