High resolution throughout the image even at maximum opening
The SIGMA 15mm F1.4 DG DN DIAGONAL FISHEYE Art has been designed according to the strict performance standards of the Sigma Art line.
It consists of 21 elements distributed in 15 groups, including several exclusive low-dispersion crystals (4 FLD and 3 SLDs) and 2 aspherical elements. By correcting the sagital comma and other aberrations, this optic can accurately reproduce bright points of light from corner to corner of the frame even to F1.4, so it is ideal for astrophotography.
Diagonal fish eye with a 180 degree view angle
The powerful distortion effect, the main attraction of the fish eyes, allows to obtain unique perspectives of the subject with a 180 degree view angle. The exceptional descriptive power of this goal, which combines an incredible 180 degree viewing angle with a very high resolution, provides a level of artistic potential that exceeds that of other fish eyes.
Designed to minimize flashes and ghost images
In order to avoid flashes (flare) and ghost images (ghosting), which reduce image quality, this optic is designed to meet all incident light conditions thanks to the tests performed with a state-of-the-art simulation technology. Resistance to strong counterlights allows clear and sharp images to be obtained under any light condition.
The most recent features and excellent construction quality
The SIGMA 15mm F1.4 DG DN DIAGONAL FISHEYE Art is equipped with several benefits to facilitate capture, like a aFL button to which you can assign a function (in compatible cameras) and a diaphragm ring equipped with a locking switch and another that allows you to cancel the click during the spin.
Also use a hLA linear motor (High-response Linear Actuator or high-response linear actuator) to make the AF fast, silent and extremely accurate.
On the other hand, it has one structure sealed against dust and splashes which provides a great robustness with a high level of resistance to weather agents, as well as an excellent quality of construction that allows to use it with guarantees for long periods in any environment.
To support the relatively heavy optical system and improve the robustness and reliability of the equipment, metal parts are used in key parts.
The TSC polycarbonate (thermally stable compound), which has a thermal contraction rate equivalent to that of aluminum, is optimally used to reduce the weight of the set. Each control element, such as rings and switches, is designed to provide a pleasant touch.
A new F1.4 optic from the Art range, carefully optimized for astrophotography
