  • Four significant technologies converge to produce the J35x11B and the J35x15B portable production lens system that has been tailored to partner with today's highest performing SDTV 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-IFxs 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

  • 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 encoders ensures high precision and repeatability of the Zoom and Focus settings

    • 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

    • A range of digital control accessories are available for this lens

  • Mechanical Technologies
    Innovative ergonomic mechanical design produced this SDTV lens with a weight under 10lbs and a relatively compact size that facilitates a wide range of applications.

    • 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.
