Precision Aberration Correction
Sigma's renowned expertise in advanced optical engineering is on full display with this lens. The intricate arrangement of 21 elements in 15 groups, which incorporates exclusive low-dispersion and aspherical glass components, renders images sharp from edge-to-edge even when shooting wide open.

Specialized Astrophotography Features
Going beyond its game-changing F1.4 aperture capabilities, Sigma designed the 15mm prime with astrophotographers specifically in mind. Rear filter slots, lens heating functionality, and a removable Arca-Swiss tripod foot facilitate multi-hour shoots in harsh nighttime environments, while suppressing flare and ghosting.

Swift Autofocus, Steady Shooting
Despite its advanced optics and solid metal housing, the 15mm Art Fisheye still clocks in at just 1.7 lbs. Photographers will appreciate both its precise autofocus driven by High Response Linear AF motors, and the incorporation of controls like the aperture ring and AFL button for quick setting adjustments on the fly.

For Sony E and Leica L shooters wanting to capture the world in an immersive, cinematic 180 degrees, or pursue astro and nightscape images like never before possible in a fisheye, Sigma's one-of-a-kind 15mm F1.4 Art lens is the ultimate creative tool.
