Canon HJ22ex7.6b 7.6-167mm Portable HDTV Production Lens, 22x Zoom Ratio

The Canon HJ22ex7.6b is a flexible multipurpose lens exhibiting high optical performance and ease of 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.

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 1.81kg 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.

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 chromatic 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.

Enhanced Digital Drive Unit
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.

Enhanced Digital Functions
Shuttle Shot
By memorizing any two focal lengths, the Digital Drive can automatically "shuttle" between the two points, moving in either direction.

Frame Preset
An angle of view can be preset in either of two memories and the lens will zoom at the highest speed or in a preset zoom speed to the preset position by pushing a simple button.

Speed Preset
A specific zoom speed can be preset in memory and it is possible to repeat the zoom speed as often as you like by pushing a simple button.
