Two aspherical elements are featured to control spherical aberrations and distortion in order to produce notable sharpness and resolution.

Nano Crystal and Super Integrated coatings have been applied to lens elements to minimize surface and internal reflections for a marked reduction in lens flare and ghosting.

Silent Wave Motor affords quick, quiet, and precise autofocus performance along with full-time manual focus override. A rear focusing design is also used, where only the rear lens group is moved during focusing, to maintain the overall length of the lens during use and to promote faster focusing speeds.

Q: 10. if your photographing people is there any distortion on the edges?

A: Like every other rectilinear (non-fisheye) ultra wide angle lens, this lens too will not be kind to people's heads at the edges of the frame. That result, which is of course undesirable, is not the fault of this lens or any other, the fault is in being too close to the people. This lens is no better and also no worse than the alternatives. It can be corrected in some software, like DxO Optics Pro. DxO included that correction a few years before this lens was released - because it is a problem with ultrawides in general, specifically with an improper use of ultrawides.
