Three SLD glass elements are employed for effective compensation of colour aberration, a common problem with super-wide angle lenses. One molded glass element and two hybrid aspherical lenses, offer excellent correction for distortion, as well as all types of aberration.
This lens is equipped with HSM technology providing quiet, high speed autofocus while offering full time manual focusing.
The non-rotating lens barrel is eminently suitable for the petal shaped lens hood (included) and circular polarizing filters.
It has a minimum focusing distance of 24cm at all focal lengths makes this lens ideal for ultra wide, close up photography.
