SIGMA 10mm F2.8 EX DC FISHEYE HSM for Canon

This extremely wide professional EX class lens, by the well-known Japanese company Sigma, is designed as a full-frame fisheye lens. This means that an image here, unlike circular type lenses, covers the entire frame. You will use its typical distortion when shooting landscapes, close-ups and in many other cases. It is regulated by a Super Multi Layer (SML) anti-reflective layer, which minimizes light reflections from the Sensor. It also boasts excellent depth sharpness.
Autofocus uses an ultrasonic micromotor,  typical for high speed and accuracy, which is also very quiet. It is intended for a wide range of digital SLR cameras compatible with the bayonet. The lens has a fixed focal length of 10mm and aperture f/2.8. To minimize light reflections you can use the sun visor, which is included.
