This lens is the world's first F1.4 diagonal fisheye interchangeable lens designed for 35mm full-frame cameras. It offers unparalleled resolving power and high resolution across the entire image, even when wide-open, making it perfect for astrophotography.
The Manual Focus Lock (MFL) switch is a feature that locks the focus once it has been acquired, preventing it from being changed by unintentional movement of the ring. This is particularly useful for long exposures and other situations where the focus should be fixed while shooting.
The lens is constructed with 21 elements in 15 groups, including 4 FLD and 3 SLD exclusive low-dispersion glass elements, and 2 aspherical lens elements. These elements work together to correct various aberrations, ensuring precise reproduction of bright points of light across the whole frame, even when wide-open.
Yes, the lens is equipped with a dust and splash-resistant structure and a water and oil repellent coating on the front element, ensuring robustness and reliability in harsh outdoor environments.
Absolutely! Its ultra-fast F1.4 aperture and 180-degree angle-of-view make it perfect for capturing breathtaking landscapes and architectural marvels.

Introducing a trailblazing prime lens from Sigma's acclaimed Art series - the 15mm F1.4 DG DN Diagonal Fisheye, engineered specifically for full frame mirrorless cameras. As the first fisheye lens of its kind with an extraordinarily bright F1.4 aperture, it empowers photographers to capture sweeping 180-degree perspectives in low light scenarios never before possible.

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.

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.

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.
