Low-cost 2/3" HD lens for a wide range of applications, from ENG Broadcast to independent professionals.

With 8.2mm, it is Canon's most angular lens in the 20x zoom range and covers a wide range of focal lengths, especially when combined with the integrated 2x Extender, which extends its focal length from 8.2mm-164mm to 16.4mm-328mm. MOD is 0.9M and the lens is equipped with a macro that allows you to place objects as close as 10mm from the front lens of the objective.

The servo motor is built to suppress noise. In the drive unit, the "Memo" switch sets the specific zoom positions for the Shuttle Shot function. The "Memo" switch allows more reliable configuration of the Shuttle Shot in the field, where more consistent operation of the controls is required.

The excellent optical performance of this ENG lens is the result of the world's leading design tools, including state-of-the-art 3D design and optical simulation technologies, new materials and coatings, and outstanding low dispersion glass. Together, these technologies and materials have produced a combination of exceptional performance in the KJ20x8.2B IRSD. The lens has minimized axial and lateral chromatic aberrations, chroma aberrations and geometric distortion. The new optical materials and multilayer optical coatings used in the lens effectively reduce the ghost glare, glare and veil that can be generated by very powerful light sources: the sun during the day and car lights at night, for example.

The KJ20x8.2B also has a high MTF (modulation transfer function) in the image.
