The Canon HJ22 ex7.6B IRSE A/IASE A is the longest focal length portable HDTV production lens by Canon (without an image stabilization system). It is a smaller and lighter replacement for the highly popular HJ21ex7.8B lens.
Long portable ENG/EFP lens
The Canon HJ22Â ex7.6B IRSE A/IASE A is intended for producers and broadcasters requiring the ability to shoot over long distances combined with wide angle capture. It provides both of these in a lightweight (1.81kg) portable lens system having exceptional HDTV performance.
This lens mobilizes the best in portable optical design criteria 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.
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.
Power Optics – 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 – superb performer for both 16:9 widescreen and standard 4:3 image formats.
Digital Technologies
New third-generation enhanced digital servo systems using Canon-developed 16-bit optical rotary encoder devices introduce new 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. A 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.
