Details
Built-in 2x Extender
This is especially important for journalism and production applications seeking cost-effective HD acquisition systems within limited budgets.
Outstanding Optical Performance
The KJ20x8.2B IRSD exhibits a high MTF at picture center that is also well-controlled out to picture extremities. The design optimization maintains that high MTF with operational adjustments of focal length and object distance.
Widest Angle
8.2mm Angle of View is widest angle of any lens in its class.
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.
Features:
- B4 lens mount for use with 2/3" format camcorders
- Offers a focal length range of 8.2-164mm
- Built-in 2x extender enhances focal length from 8.2-164mm to 16.4-328mm
- Maximum Zoom Speed 1.0 sec. from wide end to tele end
- Made from high-quality design tools including optical-simulation and 3D-design technologies, novel optical glass materials and coatings, and dispersion glass
- Minimizes longitudinal and lateral chromatic aberrations, monochromatic aberrations like coma and astigmatism, and geometric distortion
- Optical materials and multilayer optical coatings weaken optical artifacts stimulated by strong light sources
- High MTF at picture center controls picture extremities
- Macro focusing ability effectively reduces the minimum object distance to only 10 mm (from the front of the lens)
- Suitable in the fields of journalism and production
