I have read and understand the information above, and wish to download the designated software.
The primary technologies that form the underpinnings of Canon's larger HD studio lenses have all been preserved in this new compact DIGI SUPER 22xs and they include:
Newly developed materials (including Canon's high index ultra low dispersion material) combined with the very latest in element design innovations and multilayer coatings produce an unsurpassed pristine imaging system for the most discerning production team. The HDxs logo identifies the deployment of all of these technologies in the lens.
- Power Optics - speaks to the combination of specialized materials, contemporary optical design, and multilayer coatings that produce the superb imagery
- Internal Focus - a Canon design innovation that uses a floating optical system to better control chromatic aberrations
- Crossover Technology - switchable operation between 16:9 and 4:3 aspect ratio imagery
- 4-position Turret - a switchable system controlled from the associated camera that can switch in the optical extender system or the aspect ratio converter (an additional position allows for future new possibilities)
Second-generation precision digital servo systems using Canon-developed miniature 16-bit optical rotary encoder devices
- Ensures high precision and repeatability of the Zoom and Focus settings
- Encoders report to the 32-bit CPU - which, in turn, calculates during the focusing actuation to tightly control a synchronized zoom counter action that eliminates focus "breathing" (undesired change of angle of view that can accompany focus changes). This Constant Angle Focusing System is identified by the CAFS logo
- 16-bit optical rotary encoder for aperture control reports to the associated camera Iris control system (10-bit compatibility)
- 16-bit encoders are output on a special 20-pin connector for direct digital interface to Robotic and Virtual studio systems
- Facilitates a wide range of customized control characteristics and automatic recall of precision control settings when used in conjunction with Canon digital controllers for Zoom and Focus
a breakthrough ergonomic mechanical design that exploited Power Optic technologies to achieve an overall physical package that looks superb when mounted on any of the contemporary SDTV and HDTV portable production camera heads.
- Effective elimination of center of gravity variations with focus movement (using Canon's advanced 3 group Internal Focusing system)
- Carefully sealed optics offers protection against dust, smoke, and other air-contaminants
- Innovative electrical sealing offers protection against radio interference
All contemporary Canon lenses avoid the use of materials and substances potentially harmful to the environment. Lead has been removed from all optics and other identified substances from all components comprising the composite lens system.
