HJ17ex7.6B

In recent years, demand for HD production has steadily expanded to encompass a broad variety of program genres. Under such circumstances, the HJ17ex7.6B has seen a worldwide rise in popularity as a standard HD lens having high performance and ease of operation.

The HJ17ex7.6B is a lens whose central design criteria were low weight and small physical size to support greater mobility especially for HD newsgathering. It also provides a short MOD of only 0.56m in response to a strong market request. With its high optical imaging qualities the HJ17ex7.6B is distinguished within the HDxs lens series by a high price performance ratio that facilitates many forms of HD program origination.

A newly developed digital drive-unit further streamlines the lens ergonomics and ease of operation that empowers camera operator shooting flexibility.

(New drive is loaded with the lens that has ‘A’ at the end of its model name such as ‘IRSE A’, ‘IASE A’.)

Main Features

Realization of Miniaturization and Weight Reduction

The new design achieved a reduction in size that produced a total length of 206.4mm while also reducing the weight of the lens to 1.60kg (IRSE A type) which is crucial to more mobile shooting. Attention to the lens front end design in the form of an optical port diameter of only 82mm and a hood reduced in size so as to not occlude the camera operators viewing of the scene while shooting, further contribute to the dynamic shooting capabilities of the lens.

functions.

By reducing the minimum object distance to 0.56m the lens can be better utilized within confined spaces allowing objects to be effectively imaged at short distances while operating with a wide angle of view facilitated by the minimum 7.6mm focal length. Design improvements have lowered optical aberrations at the wider angle and open aperture settings.

High Optical Performance

Accumulated design experiences allied with advances in optical technologies and manufacturing techniques have contributed to a higher level of overall imaging performance in the HJ17ex7.6B

lens. In addition to providing a wider field of view some chromatic and monochromatic aberrationsShort M.O.D. 0.56m have been reduced. 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 a shorter MOD and improved resolution at the picture extremities especially over the middle to telephoto focal range.

Improved Operability & Reduced Operator Fatigue

Refined by long-term market research and worldwide experience, Canon mobilized the latest in 3D CAD-CAM design to significantly improve

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.
