HJ22ex7.6B IRSE A / IASE A

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.
	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.
	New Ergonomic Drive Unit
	Besides the exceptional optical performance, another remarkable character of this new lens is it’s newly designed drive unit. With the goal of pursuing ease of operation, Canon has reached a new design based on human ergonomics, refined by a long term research and testing. Of course, all the advantages from the current e-HDxs Digital Drive Unit such as "Information Display for user customize setting", "Rotary Encoder for virtual studio integration and precise control" and "Enhanced Digital Functions" are inherited to the new drive unit.
