Canon HJ40x10B IASD-V 40x 2/3" HD EFP Lens w/ 2x Extender, Full Servo Kit comes with Supporter (SUP-300) , SS-41-IASD and Transit Case.

The HJ40x10B and the companion highly telephoto HJ40x14B represent the pinnacle of Canon portable high definition EFP lens design.

These lenses are intended for producers and broadcasters engaged in documentary, natural history, and the many other challenging location productions that seek superb image capture over very considerable distances. These lenses embody superb built-in image stabilization systems that have become industry renowned. Aerial shooting, sports and entertainment coverage, portable acquisition in arduous terrain and under dynamic environmental situations (heavy winds) - are all superbly supported by these stalwart HD lenses.

ABOUT THIS LENS
The HJ40x10B and the companion HJ40x14B are a high definition EFP lens family that brings entirely new shooting flexibilities to field production. The HJ40x10B can extend to 770mm with the extender while the HJ40x14B can achieve an unprecedented 1120mm. Both lenses represent the very best in optical and mechanical design and their unique optical image stabilization systems make possible the capture of rock steady high definition imagery under the most adverse of field conditions.

They represent an excellent marriage of needs for creative flexibility and mobility in a handheld HDTV camera system with the demanding performance requirements for high-end HDTV image acquisition at long focal lengths. 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.

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.

• Five significant technologies converge to produce the HJ40x10B and the HJ40x14B 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
  • Crossover Technology - switchable operation between 16:9 and 4:3 aspect ratio imagery
• Image Stabilization Technologies
  A built-in Optical Shift Image Stabilizer (identified by the Shift-IS logo) system that effectively removes image stabilities especially at the telephoto extremes of the lens
• 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
• 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 from all components comprising the composite lens system.
