Design and Features
Rectilinear full-frame wide-angle zoom lens with widest angle of view ever made for full-frame digital SLR cameras.
The lens is a part of Canon’s series of Luxury lenses notable for their excellent build quality and robust design. The lens barrel is heavy, 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 AF/MF focus mode switch.
|AF||Autofocus mode with Full-Time Manual Focus.|
|MF||Manual focus mode.|
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.
A fluorine coating has been applied to the outer surfaces of the front and rear lens elements to repel particles of dust, water or oil drops for easier cleaning of the lens surfaces.
