Canon's proprietary optical technology that realizes high

image quality EF cinema lenses*

Aspherical lens manufacturing technology

Spherical lens refracts more in the periphery portions than in the center.

For that reason, it is impossible to collect a beam of light at the optimal

Focal point alignment with

aspherical lens

corrected by combining multiple lenses. On the other hands, the

aspherical lens can collect the light that passes through both the center

portion of the lens and the periphery portion of the lens at one point. The

performance obtained by using several spherical lenses can be achieved

using a single aspheric lens. Therefore, the number of lenses in the entire

lens conﬁguration can be reduced. This technology contributes to a

reduction in the size and weight of the lenses and at the same time

optical performance. Canon produces high-performance aspherical lenses

by means of advanced manufacturing technologies such as aspherical

surface grinding and glass molding processes.

Reducing changes in angle of view to enable stable framing

The CN7x17 KAS S has adopted the inner-focus-type lens formed by a three-lens group, which is a highly proven conﬁguration for

broadcast and cinema applications. The lens reduces changes in angle of view that are caused by focusing.
