HJ18ex28B IASE A
The HJ18ex28B IASE is a truly unique new Super Telephoto portable high definition EFP lens.
This lens is intended for producers and broadcasters who cover special events, concerts, documentaries, natural history, and the many other challenging location productions that seek superb image capture over very considerable distances using highly mobile HD acquisition systems. Weighing in at only 5.5 lbs and an overall length of 10.5 inches this remarkable lens offers the longest focal length of any lens in its class. And requires no mechanical support system to mount to the HD camera. Aerial shooting (using stabilized gimbals), sports and entertainment coverage, and portable HD acquisition in arduous terrain – are all superbly supported by this low-weight compact lens.
ABOUT THIS LENS
The HJ18ex28B IASE is a high definition EFP lens that brings entirely new shooting flexibilities to field production. The HJ18ex28B can extend to 500mm focal length (and to 1000mm with the extender). It has a very impressive optical speed of F2.8 up to a focal length of 286mm. The lens represents the very best in contemporary optical and mechanical design.
The lens combines creative flexibility and mobility in a portable HDTV camera system with the demanding performance requirements for high-end HDTV image acquisition at long focal lengths. The design optimization strategies include a very respectable sensitivity, maximization of image contrast, and preservation of the highest MTF over the long focal ranges.
High contrast is ensured by superb control of black reproduction – with optical and mechanical design innovations that substantially reduced flare, veiling glare, and any internal reflections. Similar attention to minimization of ghost images and other highlight-related chromatic distortions caused by strong light sources on-axis and off-axis further extend the operational contrast range of the lens.
Features
Four significant technologies converge to produce the HJ18ex28B IASE A portable HD production lens system that has been tailored to partner with today's highest performing HDTV portable cameras and camcorders:
Optical Technologies
Newly developed optical materials combined with the very latest lens element design innovations and multilayer coatings - that produce an unsurpassed pristine imaging system for the most discerning production team. The e-HDxs logo identifies the deployment of these technologies in the lens.
Power Optics
speaks to the 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 entirely new value-added 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 charged with creative shaping of the image presented to the camera sensors
16-bit rotary encoder for aperture control reports to the associated camera Iris control system (10-bit compatibility)
Maximum Zoom speed is 0.5 seconds and Focus is 1.5 seconds
Built-in Iris, Zoom, and Focus motors
Mechanical Technologies
Ergonomic mechanical design that produced this HD lens having the same size and weight as its SDTV predecessor
Compact digital servo drive unit is mounted to the lens at a 12.5 degree angle for comfort and balance
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 such as cadmium, mercury, PBBS etc from all components comprising the composite lens system.
