Optical Technologies
- 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

The DIGI SUPER 22 xs is a totally new innovation in HDTV studio lens design - one that introduces an important new choice of studio system configuration.
This XJ22x7.3BIE-D lens embodies a novel new design that anticipates the rapidly growing popularity of portable cameras being deployed for mainstream studio application. It is intended for broadcasters and producers having as their foremost priority a high-performance but cost-effective and compact HDTV studio lens-camera package that can be supported on a modest size pedestal or sturdy tripod system. This low-weight combination is also ideal for robotic system applications.
The XJ22x7.3BIE-D utilized new computer-aided optical and mechanical design techniques to produce a compact bona fide studio lens that directly couples to a portable production camera without the necessity of the traditional support “sled” apparatus.
The XJ22x7.3BIE-D is a high-end optical system squarely based upon classic studio lens design principles but carefully constrained to a physical size and weight commensurate with that of contemporary portable production cameras (that typically weigh in at about 15lbs). The more severe physical constraints of portable EFP/ENG design did not apply to this lens. Instead, a wide 105mm input optical port and novel new optical design has produced a high sensitivity, high contrast, and optimized uniformity of brightness across the image plane that is truly impressive for such a compact lens. Weighing in at 13.4 lbs (about twice that of a HD portable lens) the lens is still only a quarter the weight of a typical HD studio box lens.
The coordinated optimization of the MTF profile, contrast, and relative light illumination followed high-end studio design guidelines that ensure high picture sharpness over the image plane. Contrast was extended by superb control of black reproduction – with optical and mechanical design innovations that substantially reduced flare, veiling glare, and any internal reflections. Similar attention to minimization of ghost images and other highlight-related chromatic distortions caused by strong light sources on-axis and off-axis further extend the operational contrast range of the lens.
Finally, the important requirement of low geometric distortion at wide-angle settings constituted another central design imperative and an exemplary performance in this area has been achieved by Canon’s advanced three-group internal focusing system (which also minimizes alterations of chromatic aberrations during the focusing action).
