180˚ of high resolution
An innovative diagonal fisheye lens

The world's first* F1.4 diagonal fisheye interchangeable lens for 35mm full-frame.
Unparalleled resolving power that overturns the conventional wisdom about fisheye lenses.

In developing a fisheye lens featuring an ultra-wide-angle and powerful fisheye distortion, SIGMA has achieved a completely new level of artistic potential, combining the world's first F1.4 aperture for consumer use with outstanding resolving power across the entire image. In terms of optical performance, the SIGMA 15mm F1.4 DG DN DIAGONAL FISHEYE | Art has achieved excellent point image reproducibility and high resolution by correcting various aberrations, especially sagittal coma flare. The lens is capable of handling starscape photography, which demands particularly high-quality performance, even when wide-open. Unlike conventional fisheyes, the SIGMA 15mm F1.4 DG DN DIAGONAL FISHEYE | Art is exceptionally sharp across its entire 180° angle-of-view and offers an ultra-fast F1.4 aperture, making it perfect for a wide range of applications including astrophotography, landscapes and architecture. The expressive power of this all-new full-frame mirrorless lens opens a wealth of creative possibilities in wide-angle photography.
