Optical technology based on 50 years of experience gave rise to an extremely wide-angle lens and light for a full frame or APS-C cameras. These essential qualities are ideal for landscape photography, astrophotography, and local events photography in low light. Thanks silent ostřícímu engine on the principle of ultrasonic waves is also suitable for shooting video.
Optical technologies based on 50 years of experience have enabled Sigma to create this extremely wide-angle and super-fast lens for full-frame or APS-C cameras. With these essential characteristics, the lens is ideal for landscape photography, astrophotography, and action photography in low-light conditions. Due to its silently focusing motor based on ultrasonic waves, it is also suitable for shooting video.
The latest optical construction has been designed to achieve maximum performance even in the most critical parts of the image, minimising spherical aberration, axial chromatic aberration and field curvature, so it produces superior image quality with absolute certainty. These results have been achieved due to the fluoridated glass with Low Dispersion (FLD) and five special glasses with Low Dispersion (SLD), 15 elements in 11 groups.
