The Canon 8.5-170mm KJ20x8.5B KRSD A HDgc Series HDTV Lens is a compact and a light-weight lens that features a 20x zoom ratio, 8.5-170mm focal length, and a M.O.D of 2.95' (0.9m). It offers good MTF and resolution, along with high contrast from the center of the image to its extreme edges.

Shuttle Shot Function
Shuttle Shot is a Canon Technology that enhances production capabilities. At the touch of a button, this feature allows the operator to zoom back and forth instantly between any 2 positions. It can be used to zoom to the telephoto position to check focus and then return instantly to the original position or you can shuttle between any 2 zoom positions at any time.
Compact Design
This lens is smaller in size and lighter in weight, which allows ease of use when carried on a shoulder.
Advanced Drive Unit
The KJ20x8.5B KRSD A is fitted with a camera-communication interface to support the separate aberration correction functions. The KJ20x8.5B KRSD A's zoom can travel end to end in 1.0 seconds. The advanced drive unit's push switch (previously memo switch) can be used for setting specific zoom positions for the Shuttle Shot function. The memo switch enables reliable Shuttle Shot setup in the field where more consistent functioning of the controls is required.
