Sigma 15mm F1.4 DG DN Diagonal Fisheye Art Series Lens for L Mount

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 astrophotography, 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. 

Resolving power that overturns the conventional wisdom about fisheye lenses
The latest optical design thoroughly corrects each type of aberration. This diagonal fisheye lens has the unique expressiveness of a fisheye lens and high resolution throughout the entire image from a wide-open aperture. The performance of the lens is guaranteed by a full inspection with Sigma's proprietary MTF measuring system.

Even wide-open, high resolution and point image reproducibility across the entire image
The lens consists of 21 elements in 15 groups, including 4 FLD and 3 SLD exclusive low-dispersion glass elements, and 2 aspherical lens elements.  By correcting sagittal coma flare and other aberrations, the lens can precisely reproduce bright points of light across the whole frame even wide-open, making it ideal for astrophotography. 

Diagonal fisheye lens with 180° angle of view
The powerful distortion effect, which is the appeal of fisheye lenses, allows users to enjoy expressions such as a unique perspective and emphasis on the subject at a 180° angle of view. In addition, the Sigma 15mm F1.4 DG DN Diagonal Fisheye | Art is designed with the strict performance standards of the Art line. Furthermore, all lenses are inspected with Sigmas proprietary MTF measuring system. The unique descriptive power of this new fisheye lens, which combines an incredible 180° angle-of-view with very high resolution optics, delivers a level of artistic potential that exceeds other fisheye lenses.

Designed to minimize flare and ghosting
To prevent flare and ghosting, which reduce image quality, the lens is designed to handle all conditions of incident light based on state-of-the-art simulation technology. High backlight resistance enables clear and sharp images under any lighting conditions.
