HJ22ex7.6B IASE Overview

The HJ22ex7.6B is the longest focal length portable HDTV production lens offered by Canon (without an image stabilization system). It is a smaller and lighter replacement for the former highly popular HJ21ex7.8B lens. It is a strategic member of the family of HD portable EFP lenses – that collectively offers an unusually broad range of creative options. This particular lens is intended for producers and broadcasters having as their foremost priority the ability to shoot over long distances combined with wide angle capture in a lightweight (4.0 lbs) mobile production lens system having exceptional HDTV performance. The optional flexibility of Canon’s Crossover aspect ratio switching system makes it a superb performer for both 16:9 widescreen and standard 4:3 image formats. ABOUT THIS LENS The HJ22ex7.6B mobilized the best in portable EFP optical design criteria to achieve a remarkable lens offering focal lengths up to 168mm (or 336mm with extender) and a wide-angle of 64.6 degrees horizontal (for the 16:9 aspect ratio). Combined with an exceptionally high sensitivity (F1.8 maximum aperture) this is a lens that can encompass an unusually broad range of shooting situations. The design optimization strategies sought a high and balanced MTF profile over the entire image plane at an approximate F4.0 aperture setting that is well-maintained even when the lens aperture is wide open. Relative light distribution was optimized for F2.8 and above and this uniformity of brightness across the image plane combines with the high contrast and excellent picture sharpness to produce vividly clear HD pictures. 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.

HJ22ex7.6B IASE

Four significant technologies converge to produce the HJ22ex7.6B portable HD production lens system that has been tailored to partner with today's highest performing HDTV portable cameras and camcorders:

Optical Technologies

Newly developed optical materials combined with the very latest lens element design innovations and multilayer coatings - that produce an unsurpassed pristine imaging system for the most discerning production team. The e-HDxs logo identifies the deployment 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 Option - switchable operation between 16:9 and 4:3 aspect ratio imagery

Digital Technologies

New third-generation enhanced digital servo systems using Canon-developed 16-bit optical rotary encoder devices introduce entirely new value-added creativity to handheld acquisition systems Enhanced Digital Drive technology - encompasses a microcomputer driven servo control that embodies position memory and user-defined digital functionality to significantly empower the camera operator charged with creative shaping of the image presented to the camera sensors 16-bit rotary encoder for aperture control reports to the associated camera Iris control system (10-bit compatibility) Maximum Zoom speed is 0.5 seconds and Focus is 1.5 seconds

Mechanical Technologies

Ergonomic mechanical design that produced this HD lens having the same size and weight as its SDTV predecessor Compact digital servo drive unit is mounted to the lens at a 12.5 degree angle for comfort and balance Magnesium alloy body for light weight and exceptional durability

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.
