Sigma 15mm f/2.8 EX DG Diagonal Fisheye Lens
Creative Wide-Angle for Bold Photography
The Sigma 15mm f/2.8 EX DG Diagonal Fisheye Lens is designed for photographers who want to push creative boundaries. With its 180° diagonal field of view, this lens transforms ordinary scenes into extraordinary works of art. Whether you’re shooting landscapes, interiors, abstract compositions, or unique portraiture, the Sigma 15mm fisheye offers a distinctive perspective that makes your work stand out.
180° Diagonal Field of View
The defining feature of the Sigma 15mm f/2.8 EX DG is its ultra-wide fisheye perspective. Capturing a full 180° angle, this lens bends straight lines into dramatic curves, creating the signature fisheye effect loved by creative photographers and filmmakers.
Unlike standard wide-angle lenses, the fisheye effect introduces an artistic distortion that can turn even the most common subjects into fascinating visuals. Photographers in the USA who specialize in architecture, landscape, and action sports photography love this lens for its ability to create immersive and dynamic imagery.
Fast f/2.8 Aperture for Low-Light
The bright f/2.8 maximum aperture ensures that the Sigma 15mm fisheye performs exceptionally well in low-light environments. Whether you’re capturing indoor events, night cityscapes, or astrophotography experiments, the wide aperture allows plenty of light into the sensor, reducing the need for high ISO and delivering clean, detailed images.
This aperture also offers control over depth of field, making it possible to isolate subjects while still maintaining the unique fisheye look.
Optimized Optical Design
Built with 7 elements in 6 groups, the Sigma 15mm f/2.8 EX DG is designed to minimize chromatic aberrations and maintain sharpness across the frame. The multi-layer coating reduces flare and ghosting, delivering high-contrast and color-accurate images even when shooting against bright light sources.
The lens is also optimized for digital cameras (DG series), ensuring excellent image quality on both full-frame and APS-C sensors.
Close Focusing for Creative Macro Effects
Another standout feature is its close focusing distance of just 5.9 inches (15 cm). This allows photographers to create exaggerated close-up images with a fisheye perspective. From dynamic wide-angle portraits to creative shots of objects, the Sigma 15mm opens endless artistic opportunities.
Build Quality – EX Series Design
As part of Sigma’s EX (Excellence) series, the 15mm f/2.8 DG fisheye is built for durability and professional use. Its compact, lightweight design makes it easy to carry for travel, adventure, and action photography. The solid construction ensures longevity, while the built-in petal hood helps reduce flare and protect the front element.
