All lenses are equipped with an informational display and Digital Function Selector, an X-Y axis switch, so that the user can customize the enhanced digital functions much more easily and precisely. This new design enables the user to fully bring out the digital functions.
Main Featur es
By memorizing any two focal lengths, the Digital Drive can automatically "shuttle" between the two points, moving in either direction.
An angle of view can be preset in either of two memories and the lens will zoom to that position by pushing a simple button. During a performance, framing preset will reproduce the zoom position decided upon at the rehearsal. It's easy to repeat the same zoom as often as you like at the highest speed or in a preset zoom speed.
A specific zoom speed can be preset in memory and it is possible to repeat the zoom speed as often as you like by pushing a simple button.

Digital Function Selector
Canon offers a complete series of eHDxs lenses, which are equipped with an enhanced digital drive unit. Conventional potentiometers are analog positional sensors capable of only 8-10 bit equivalent resolution. Thus virtual ENG studio systems called for an optional Encoder Unit to be put on the zoom and focus ring of the lens. With the introduction of 16 bit resolution Rotary Encoder Devices built into the new enhanced digital drive unit, the lens can simply be integrated into a virtual digital studio system without any additions. Canon's unique technology has made the Encoder Device surprisingly small to be installed in the existing drive unit without changes in size or weight.
Canon has always developed new technology with four basic philosophies, "High Quality of Picture", "Ease of Operation", "High Specification" and "Minimize Environmental Impact". Canon's HDTV lenses are, so to speak, a compilation of our basic philosophies. Canon is the only manufacturer to offer a complete line of HDTV lenses to match our customers requirements. Complete "Customer Satisfaction" is our goal.

Overall Comparison Between HDTV and SDTV
Whereas one frame of the conventional SDTV (ie NTSC) system consists of 480 scanning lines, the number of scanning lines is more than 1. 5 times that for the HDTV system.
