Canon CJ20ex7.8B IASE S

Properties:

This zoom lens has been designed with high refractive index optical glass materials, all of which have unique scattering properties and help minimize chromatic aberrations and geometric distortions. The surface accuracy of the lens elements has been significantly improved over HDTV lenses, which contributes to the improved MTF (Modulation Transfer Function) performance required for 4K images. New multilayer optical coatings combined with new deposition techniques result in an exceptionally pure optical imaging system.

• Compact and lightweight
• For 4K recordings
