Canon XJ100x9.3B HD Box Lens

The DIGISUPER 100 offers the longest zoom ratio among the family of six HDTV field lenses offered by Canon.

The XJ100x9.3B mobilized the best in optical, mechanical, and digital technologies to implement a long zoom lens that is remarkable for its relatively modest size and weight. It is a design directly responding to the expressed aesthetic desires of the world's most creative HD producers and directors - in terms of optical sensitivity, very long telephoto capability, and startling HDTV image quality. The XJ100x9.3B utilizes an exceptional built-in image stabilization system to support such triple digit zoom operations.

This lens embodies the pinnacle in dynamic image creation for live television production - for both HDTV and SDTV. It is intended for mobile truck operators and broadcasters having as their foremost priority the greatest telephoto flexibility for high definition sports and entertainment event coverage. This lens and the companion duo XJ86x9.3/XJ86x13.5B have become the industry standard among the major HDTV mobile television facilities. It can equally service the special needs of government (homeland security) and many other institutional sectors of the market that might have high resolution long telephoto as a priority.

ABOUT THIS LENS

The XJ100x9.3B design applied the most state of the art in Canon optical technologies to break a barrier in focal length range that many considered impossible. Canon's renowned engineering design optimization strategies were once again brilliantly applied to the unique technological challenges of providing full HDTV image quality while implementing an unprecedented control of focal length over the formidable range from 9.3mm to 930 mm (1860 mm with extender). The design paid particular attention to streamlining the ergonomics and physics of such a challenging optical system. The built-in optical image stabilization system (that makes such an unprecedented focal range practical) has earned enthusiastic industry acclaim.

The optimizations within the optical design successfully maintain a high MTF profile over the entire image plane when exercising the unprecedented 100:1 focal length change. A parallel optimization paid close attention to minimizing chromatic aberrations over this same focal range. Recognizing the especially challenging nature of sports and event coverage (that regularly encounter challenging low scene lighting) the lens designers also gave a special priority to achievement of an impressive maximum relative aperture.

Contrast was extended by superb control of black reproduction - with optical and mechanical design innovations that substantially reduced flare, veiling glare, and 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. The resulting superb contrast range of the lens augments its high picture sharpness. The combination ensures stunning picture clarity for sports, large events, and high-resolution surveillance imagery.

Features:

Five significant technologies form the underpinnings of the DIGI SUPER 100xs lens system that has been carefully designed to partner with today's highest performing HDTV cameras

• Optical TechnologiesNewly developed materials (including the 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 control chromatic aberrations
  • Crossover Technology Option - 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)
• Image Stabilization TechnologyThe image stabilizer feature by Canon has been faithfully used over the years at many of the world's highest-profile sporting events, and is now considered a must when shooting sports. With the XJ100x9.3B, a more advanced version of Canon's image stabilizer has been incorporated as a standard feature. With a new sensor and sped-up control circuit, this latest version of the image stabilizer significantly curbs vibration, particularly in the high-frequency range. By successfully suppressing all kinds of vibration, such as that generated by wind and excited fans in the stands, the XJ100x9.3B's image stabilizer allows the capture of stable, clear video even at super-telephoto range. It also makes camerawork a comfortable endeavor by largely mitigating the "aftershock" phenomenon that occurs when an image moves after the camera operator stops panning. The XJ100x9.3B, XJ95x and XJ80x field lenses all feature the same image stabilizer in their standard feature set, allowing them to deliver stable, beautiful images.
• Digital TechnologiesSecond-generation precision digital servo systems using Canon-developed 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 available for 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
• Mechanical TechnologiesErgonomic mechanical design that exploited Power Optic technologies to maintain the same size and weight as the predecessor HDTV field lens:
  • Effective elimination of center of gravity variations with focus movement (using Canon's advanced 3 group Internal Focusing system) further empowers the creativity of the camera operator
  • Carefully sealed optics offers protection against dust, smoke, and other air-contaminants
  • Innovative electrical sealing techniques offers Protection against radio interference
• Ecological DesignAll 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.
• Support for Virtual SystemThe XJ100x9.3B is equipped with high-performance zoom, focus, and iris encoders. With multiple support for encoder outputs, analog outputs, and serial outputs, the XJ100x9.3B can work with many kinds of virtual systems. It easily adapts to existing virtual systems because it comes standard equipped with 20-pin lens interface. The XJ100x9.3B is equipped with high-performance zoom, focus, and iris encoders.
