The lens was designed for full frame Canon SLR cameras and works like circular fisheye at focal length of 8 mm and diagonal at 15 mm. With APS-C camera 180 degree angle of view could be obtained approximately at 10 mm. The lens is also compatible with Canon APS-H SLR cameras.
The lens barrel is of moderate weight, dust-proof and water-resistant, made of metal. The lens mount is metallic.
The lens has rather narrow focal range. Formally it is the disadvantage, however in practice it contributes to a good compensation of optical aberrations and equally high image quality at the entire focal range.
The lens features a zoom lock lever to keep the zoom ring fixed at the shortest focal length of 8 mm. This function is convenient for carrying a camera with the lens on a strap because it prevents the lens from extending.
The lens features AF/MF focus mode switch.
|AF||Autofocus mode with Full-Time Manual Focus.|
|MF||Manual focus mode.|
Aspherical elements (ASPH, XA) minimize spherical aberration, astigmatism, coma and ensure excellent sharpness and contrast even at maximum aperture.
Low dispersion elements (AD, ED, LD, HLD, SD, UD etc) and fluorite elements minimize chromatic aberrations and ensure excellent sharpness and contrast even at maximum aperture.
The lens incorporates a floating system that provides correction of aberrations and ensures constantly high image quality at the entire range of focusing distances from infinity down to the closest focusing distance. Learn more
Due to the prominent convex profile of the front element the lens does not have a filter thread. However, the manufacturer provided a slip-in filter holder for cut gelatin filters at the rear of the lens.
There is a hood thread also but the hood blocks the view at 8-12 mm with full frame sensor.
