Canon KH20x6.4 KRS 1/2" HD professional lens

Description: Canon introduces their new line of 1/2-inch HDgc lenses to support the introduction of economical, mid-range HD cameras: KH20x6.4 KRS (KJ20x8.5 KRS for 2/3-inch), KH21ex5.7 IRSE and KH10ex3.6 IRSE. And while the HDgc line is engineered for affordable HD, the optical performance and operation of these lenses is anything but ordinary. The new lenses combine the best optical features of Canon’s remarkable lenses, including reduced chromatic aberration, and high and well-controlled MTF, with digital operational tools that include Shuttle Shot, Framing Preset, Speed Preset, and more in a line-up that delivers HD optical quality and other higher-end lens advancements. The HDgc lens line includes for 1/2-inchCCD cameras: the KH21ex5.7IRSE (telephoto version), theKH10ex3.6IRSE (wide angle lens), and a 16X standard version which will be available late 2006. Digital “eDrive” is available on all three of these lenses, and represents a principal difference (along with a built-in 2X extender) between these models and the more economical KH20x6.4KRS (for 1/2-inch HD CCD cameras) and the KJ20x8.5B KRS (for 2/3-inch HD CCD cameras).

Features: Shuttle Shot Function Shuttle Shot is a Canon Exclusive Technology that enhances production capabilities. At the touch of a button, this feature allows the operator to zoom back and forth instantly between any two 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 two zoom positions at any time.

Compact Design
The KH20x is smaller in size and lighter in weight compared to the traditional BCTV lenses, which allows ease of use when carried on a shoulder.

Advanced Drive Unit
The new ergonomically designed drive unit achieves an ideal balance and comfort by having it tilt to an ideal angle. In addition, the size of the unit has been minimized to comfortably fit in the palm of one’s hand. Overall, it improves the feeling of unity between the user and the lens. Moreover, the drive unit is equipped with a Shuttle Shot Function while offering a maximum zoom speed of 1.2 sec from wide end to tele end.
