Superb optical performance and handling. The HJ22ex7.6B IRSE A/IASE A is 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 HJ22ex7.6B IRSE A/IASE A is intended for producers and broadcasters requiring the ability to shoot over long distances combined with wide angle capture 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.
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
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.
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.
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.
High Specification in Compact Size
The focal range of 7.6mm to 167mm can be further extend to 334mm using the 2x range extender included in the lens. This highly flexible lens has been reduced in length to 221.5mm and in weight to 1.81 kg (IRSE A type) producing a remarkably compact package that supports a broad range of productions.
High Optical Performance
Evolving design techniques, advanced optical materials and optical coatings, and continuing refinements to manufacturing processes have collectively contributed to the HJ22ex7.6B lens having very high optical performance and extended operational capabilities. Specifically these include a lowering of longitudinal chromatic aberration at the longer focal lengths, and curtailment of spherical and comatic aberrations. Adoption of new optical materials also afforded a reduction in curvature of field. The lens focusing system has also been improved over the conventional 2-group inner focus in terms of an improved resolution and contrast at the picture extremities especially at the telephoto side of the focal range.
