Features
Internal Focus for Ultimate Versatility
Canon internal focus is made for the highest quality professional video cameras used in news and event videography. The front lens element is stationary and can be used with a matte box for greater lens flare protection, as well as a wide array of square and rectangular filters. Benefits include reduction in chromatic distortions, as well as decreases in flare.
Shuttle-Shot Technology
The lens has an added capability for zooming; using the shuttle shot-switch. At the touch of a button, the lens can move to and from a pre-programmed point. This can be used both creatively, and as a no-hassle way of verifying focus.
Integral 2x Extender
For instant close-up shots, the lens has a switch which inserts an element that doubles the focal length at any point in the zoom range. Instead of using the zoom function, the extender gives immediate close-up images.
