Canon DIGI SUPER 62 Tele SDTV Field Lens

The DIGI SUPER 62 is a new NAB2005 introduction - intended to strongly augment choices for long focal length standard definition lenses offered by Canon.

The DIGI SUPER 62 is offered in two varieties - a wide-angle PJ62x 9BIE-D and a companion long-telephoto PJ62x 13.5BIE-D. This duality will greatly extend the options available to broadcasters and producers to service a broad range of long focal length applications in the field, in large studios, and in special venues.

These lenses embody the latest in optical technologies to implement more cost-effective high-performance long zoom SDTV lenses. They are intended for mobile truck operators and broadcasters having as their foremost priority the extended telephoto flexibility for NTSC and digital standard definition sports and entertainment event coverage. They can equally service the special needs of government (homeland security) and many institutional sectors of the market that might have long telephoto as a special priority.

ABOUT THIS LENS

The DIGI SUPER 62 design applied state of the art optical technologies to produce highly contemporary SDTV lenses. Canon's renowned engineering design optimization strategies were applied to the unique technological challenges of providing maximum image quality while implementing a wide control of focal length. The design paid particular attention to streamlining the ergonomics and physics of such a challenging optical system.

The optimizations within the optical design successfully maintain a high MTF profile over the entire image plane when exercising the 62:1 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 of f 1.7.

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 entertainment events, and high-resolution surveillance imagery.

FEATURES AND TECHNOLOGIES

Four significant technologies form the underpinnings of the DIGI SUPER 62 lens system that has been carefully designed to partner with today’s highest performing SDTV cameras:

Optical Technologies - newly 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 IFxs logo identifies the deployment of all of these technologies in the lens.

Digital Technologies - second-generation precision digital servo systems using Canon-developed 16-bit optical rotary encoder devices

Mechanical Technologies - ergonomic mechanical design that exploited Power Optic technologies to maintain the same size and weight as the predecessor SDTV field lens:

Ecological Design - 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.
