A revolutionary addition to the world of photography, the 15mm f/1.4 DG DN Diagonal Fisheye Art Lens offers a unique blend of ultra-wide-angle and powerful fisheye distortion. This lens is the world's first F1.4 diagonal fisheye interchangeable lens designed for 35mm full-frame cameras, offering unparalleled resolving power that challenges traditional perceptions of fisheye lenses.
The Sigma 15mm F1.4 DG DN Diagonal Fisheye Art Lens is meticulously crafted for astrophotography, a field that requires exceptionally high-quality performance. It features an innovative optical design that corrects various aberrations, especially sagittal coma flare, ensuring excellent point image reproducibility and high resolution across the entire image, even when wide-open.
This lens is not just for astrophotographers. Its ultra-fast F1.4 aperture and 180-degree angle-of-view make it perfect for capturing breathtaking landscapes and architectural marvels. The lens's unique expressiveness and high resolution open up a wealth of creative possibilities in wide-angle photography.
Constructed with 21 elements in 15 groups, the lens includes 4 FLD and 3 SLD exclusive low-dispersion glass elements, and 2 aspherical lens elements. These elements work together to correct sagittal coma flare and other aberrations, ensuring precise reproduction of bright points of light across the whole frame, even when wide-open.
The Sigma 15mm F1.4 DG DN Diagonal Fisheye Art Lens also features a Manual Focus Lock (MFL) switch, a lens heater retainer, and a rear filter holder. The MFL switch ensures that once focus is acquired, it will not be changed by unintentional movement of the ring. The lens heater retainer prevents the lens heater from protruding over the front element, eliminating the risk of vignetting. The rear filter holder allows sheet-type filters to be used.
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. The AF actuator is a high-response linear actuator (HLA), providing fast, quiet, and highly accurate AF shooting.
In conclusion, the Sigma 15mm F1.4 DG DN Diagonal Fisheye Art Lens is a game-changer in the field of photography, offering a unique blend of ultra-wide-angle and powerful fisheye distortion, high resolution, and a wealth of advanced features. It is an excellent choice for photographers seeking to push the boundaries of their creativity.
