Canon HJ40x10B IASD-V Lens w/ Controls, Sled and Case- USED

Description

The HJ40x10B represents the pinnacle of Canon portable high definition EFP lens design. Image capture over long distances with extender can achieve 800mm and its focal length of 10mm~400 provides a wide angle that makes it very suitable for sports applications such as golf. The HJ40x10B represents the very best in optical and mechanical design and its unique optical image stabilization systems make possible the capture of rock steady high definition imagery under the most adverse of field conditions. Aerial shooting, sports and entertainment coverage, portable acquisition in arduous terrain and under dynamic environmental situations (heavy winds) – are all superbly supported by this stalwart HD lens.

The design optimization strategies included a dual lens approach to broaden the shooting options, achievement of an adequate sensitivity, maximization of image contrast, and preservation of the highest MTF over the long focal ranges.

Optical Technologies

• Power Optics – combination of specialized materials, contemporary optical design, and multilayer coatings that produce the superb imagery
• Internal Focus – a Canon design innovation that uses a floating optical system to better control chromatic aberrations

Digital Technologies

New third-generation enhanced digital servo systems using Canon-developed 16-bit optical rotary encoder devices introduce new creativity to handheld acquisition systems. Enhanced Digital Drive technology – encompasses a microcomputer driven servo control that embodies position memory and user-defined digital functionality to significantly empower the camera operator. A 16-bit rotary encoder for aperture control reports to the associated camera Iris control system (10-bit compatibility).

Mechanical Technologies

Magnesium alloy body for light weight and exceptional durability

Ecological Design

All contemporary Canon lenses avoid the use of materials and substances potentially harmful to the environment. Lead has been removed from all optics and other identified substances from all components comprising the composite lens system.

It is Canon’s policy not to pollute the earth and the HJ40x series have avoided using any materials or substances that could pollute the environment.

Optical Shift Image Stabilizer (Shift-IS)

When the lens moves, the light rays from the subject are bent relative to the optical axis,
resulting in an unsteady image because the light rays are deflected. By shifting the IS
lens group on a plane perpendicular to the optical axis to counter the degree of image shake, the light rays reaching the image plane can be steadied. Since image shake occurs in both horizontal and vertical directions, two shake detecting sensors for yaw and pitch, detect the angle and speed of movement and send this information to a high-speed 32-bit microcomputer, which converts the information into drive signals for the IS lens group. Then the actuator moves the IS lens group horizontally and vertically thus counteracting the image shake and maintaining the stable picture. The Shift-IS component is located within the lens group and is most effective for lower frequency movements caused by platform vibration or wind effect without increasing the overall size and weight of the master lens.
