Recent years have witnessed expansions in both HD production and the range of
program genres. Within this environment the worldwide popularity of the HJ22ex7.6B
lens as 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.
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.
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.
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:
