operation has grown significantly. The combination of a generous 22x zoom ratio and a wide 7.6mm field of view meets numerous challenging production applications that include dramas, documentaries, sports, news etc.

A newly developed digital drive unit has further streamlined the lens ergonomics to further empower camera operator shooting flexibility.

The new drive unit will be identified with an “A” at the end of the model name – such as

IRSE A or IASE A.
Main Features
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.

Tight Control Over Optical Aberrations

Close attention to managing a reduction in a variety of optical aberrations while also adopting an innovative new focusing system has produced an overall performance improvement over the predecessor model that benefits both HD ENG and general HD production.

The incorporation of miniature 16-bit, high resolution Rotary Encoder Devices into the new enhanced digital drive unit, has extended the features of the HJ14x to include:

• Precision control of all lens operations

• Precise digital repeatability of zoom, focus and iris control that support innovative image creation

• Simple and direct digital integration into virtual studio systems

• Precision zoom control over a total speed range of 0.5 sec. to more than 5 min.

Moreover, Canon's unique Information Display provides easy, precise customization of the enhanced digital functions.

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.

Improved Operability & Reduced Operator Fatigue

Coupled with innovations in optical performance, is a totally new design of the digital drive unit.

Refined by long-term market research and worldwide experience, Canon mobilized the latest in 3D CAD-CAM design to significantly improve the human tactile interface to the control of zoom, iris, and focus. Here are some results of Canon's research:
