Canon | KJ20x8.2B 8.2-164mm IRSD Pro Zoom | Broadcast Lens

The Canon KJ20x8.2B Portable 20x HD Lens with 2x Zoom Extender features a B4 mount for use with 2/3″ format
camcorders and offers a focal length range of 8.2-164mm. With a built-in 2x extender, you can enhance its focal length
to 16.4-328mm.
Crafted with high-quality design tools including optical-simulation and 3D-design technologies, the Canon HD lens
ensures minimal axial and lateral chromatic aberrations, coma aberrations, and geometric distortion. Furthermore, the
lens features optical materials and multilayer optical coatings that minimize optical artifacts stimulated by strong light
sources. Macro focusing ability effectively reduces the minimum object distance to only 1 Omm from the front of the
lens.

Advanced Drive Unit technology provides a convenient control when using Canon portable HD lenses. Thanks to its
ergonomic design, the drive unit touts a comfortable grip and an improved balance, which further enhances your
tactile connection with the lens.
This lens also includes Canon’s Shuttle Shot technology that improves production capabilities. Employ the Shuttle Shot
technology to rapidly zoom back and forth between any two positions. It can also be used to zoom to the telephoto
position for checking focus and almost instantly returning to the original position, or ‘shuttle’ between any two zoom-
positions at any time. You can also set specific Shuttle Shot zoom positions through a memo switch that enables
reliable Shuttle Shot setup in the field where more consistent functioning of the controls is required. Additionally, you
can securely grip the drive unit without inadvertently pressing on the VTR or Shuttle Shot buttons.
