Sigma 15mm f/1.4 Fisheye DG DN Art Lens (Sony E)

Sigma 15mm f/1.4 Fisheye DG DN Art Lens for Sony E
Flagship Diagonal Fisheye – 180° Angle of View, Ultra-Fast f/1.4 Aperture, HLA AF Motor & Astrophotography Features

The Sigma 15mm f/1.4 Fisheye DG DN Art is a high-performance diagonal fisheye prime lens engineered for full-frame Sony E-mount mirrorless cameras. Delivering an expansive 180° angle of view paired with an ultra-fast f/1.4 maximum aperture, this Art-series optic brings sweeping scope and high clarity to astrophotography, architectural interiors, dynamic landscapes, and extreme action sports. Its bright f/1.4 design enables low-light shooting while producing dramatic perspective distortion.

Its complex optical architecture incorporates 21 elements in 15 groups, including four FLD elements, three SLD elements, and two aspherical elements. This layout is optimized to maintain edge-to-edge sharpness across the entire field of view while suppressing sagittal coma flares to preserve point-light sources like stars. Autofocus is driven by Sigma’s High-response Linear Actuator (HLA) motor for fast, quiet, and precise subject tracking with low focus breathing for video workflows. Built for field use and long exposures, the weather-sealed chassis features a water- and oil-repellent front coating, a manual focus lock switch, a lens heater retainer, dual rear sheet filter slots, and a removable Arca-Swiss compatible tripod collar.

Key Features & Performance Highlights
