Canon has developed breakthrough optical design concepts using a newly developed optical element in the most effective way. We have named this design concept the “Power Optical System” which can achieve higher specifications and quality in a smaller size and lighter weight, using a unique optical “Element” which realizes complete elimination of its aberration. Thanks to the X element & Power Optical System, the J21aX7.8B is significantly smaller in size and weight compared to its predecessor offering both more telephoto and a wider angle with improved optical quality.
Shuttle Shot :
By memorizing any two focal lengths, the Digital Drive can automatically "shuttle" between the two points, moving in either direction.
Framing Preset :
An angle of view can be preset in memory 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.
Speed Preset :
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.
A new feature has been added to our “Useful” Digital Drive, called “Zoom Track”. It allows the camera operator to adjust the electronic focal length to their desired range by memorizing zoom positions at both the tele and the wide side of the zoom.
