Additional information:
The Canon EF 14 mm f/ 2.8 L II USM is an update version of an ultrawide lens with corrected distortion for Canon EOS film and digital cameras. So far, it is the widest angle lens for the Canon F bayonet mount .
As different from the first version, it features a new optical scheme with low dispersion glass elements. The minimum focusing distance has reduced by 10 cm, while the weight and length have slightly increased. Canon engineers have elaborated the aperture construction. This lens has a circular aperture which produces a better representation of out-of-focus areas(bokeh).
The lens is made of lead-free glass.
With a 2.8 lens speed the lens enables you to photograph in a better and simpler way even in poor lighting conditions without a tripod or a flash.
It is rather sharp at f/2.8. And it is very sharp from f/4 onwards.
Distortion is insignificant. The optical scheme includes two aspherical elements for its correction.
There is a loss of detailing visible at the corners, but it is not as considerable as that in the first version.
A built-in ring-type ultra-sonic motor makes focusing fast and virtually silent. Focusing is internal. You may switch from AF to MF mode any time with a rubber-coated ring. During autofocusing operationg the ring does not rotate, so there can be no involuntary defocusing.
The front convex element makes it impossible to attach filters. Delatin filters can be used in the rear part of the lens.
It provides beautiful color rendering, and is well resistant to back and side light. It is equipped with a small built-in petal-type hood.
The Canon EF 14mm f/2.8L II USM is ideal for landscape, architecture, interior and genre photography.
It is dust and moisture resistant.
The lens comes completed with a hood and a soft case.
