Basic Information

Product Features

Unparalleled resolving power that overturns the conventional wisdom of fisheye lenses
World's first* 35mm full size compatible F1.4 diagonal fisheye lens

*As an interchangeable lens for consumer-use 35mm full-frame cameras. (As of February 2024, according to our research)

- Resolving power that overturns the conventional wisdom of fisheye lenses
The latest optical design thoroughly corrects each aberration. This diagonal fisheye lens offers the unique expressiveness of a fisheye lens and high resolving power throughout the entire image from wide-open to wide-open. The performance of the lens is guaranteed by Sigma's unique MTF measuring instrument.

- High resolving power and point image reproducibility from wide open to the entire image
Luxurious lens construction with 21 elements in 15 groups including 4 FLDs, 3 SLDs, and 2 aspherical lenses made of special low-dispersion glass. By correcting sagittal coma flare and other aberrations well, the lens achieves high resolution and point image reproducibility that can withstand star photography from wide open to the entire image.

- Diagonal Fisheye Lens with 180° angle of view
The powerful distortion effect that is the charm of fisheye lenses allows photographers to enjoy 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 to the strict standards of the Art line in terms of performance. In addition, all lenses are tested using SIGMA's proprietary MTF measuring equipment. The one-of-a-kind descriptive power of the DIAGONAL DIAGONAL FISHEYE Art, combining the unique expressiveness of a fisheye lens with amazingly high resolution, achieves an expression beyond the conventional wisdom of fisheye lenses.

- Flare and Ghosting-Friendly Design
To prevent flare and ghosting, which reduce image quality, we have taken countermeasures against all conditions of incident light based on the most advanced simulation technology. High backlight resistance enables clear and sharp images under any lighting conditions.

- Equipped with the latest functions and high build quality.
The camera is equipped with various functions to assist shooting, including an AFL button*1 to which any function can be assigned, an aperture ring, etc. A linear motor HLA (High-response Linear Actuator) is used for the AF actuator, enabling fast, quiet, and highly precise AF shooting. The camera has a dustproof and drip-proof construction*2 to ensure high weather resistance and robustness, and has a high build quality that allows it to be used reliably over a long period of time in any environment.

*1 Only compatible cameras can be used. Also, the functions that can be assigned vary depending on the camera.
*2 The construction is designed to be dustproof and drip-proof, but not waterproof.

- Various shooting assist functions
The camera is equipped with an AFL button to which any function can be assigned. In addition to the aperture ring, the camera is equipped with an aperture ring lock switch and a click switch to turn the aperture ring on and off.
Dustproof and drip-proof construction with water and stain repellent coating
In addition to the dustproof and drip-proof body, the front-most surface of the lens is coated with a water and dirt repellent coating, allowing photographers to shoot safely even in harsh outdoor environments.

- Adoption of linear motor HLA
A linear motor HLA (High-response Linear Actuator) is used as the AF actuator. The high-thrust motor and advanced electronic control enable the focus lens to operate at high speed and with high precision, providing comfortable AF shooting.

- High build quality
To support the heavy optical system and enhance robustness and reliability, metal parts are used in key parts of the body. On the other hand, lightweight engineering plastic TSC* is also used in appropriate places to reduce weight. Each operation part, such as rings and switches, is designed to feel good to the touch. SIGMA is proud of the high build quality of this product, which does not compromise on durability, operability, or the highly satisfying ownership experience.
Polycarbonate has the same heat shrinkage rate as aluminum. It has high affinity with metal parts and contributes to the creation of high-precision products.
