Canon CN7×17KAS S Specifications

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
one point. This is called spherical aberration, and this aberration can be
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 Spherical aberration of
makes it possible to produce sharp images owing to its outstanding
spherical lens
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.
3-group inner focus system established for broadcast and cinema use

The development of glass materials with an anomalous dispersion
In theory, chromatic aberration cannot be completely
eliminated in standard optical glass, and a slight characteristic similar to fluorite has been progressing recently. These efforts
