Features- Two significant technologies converge to produce the HJ11x4.7B KLL-SC lens system that has been specifically tailored to partner with todays highest performing HD portable cameras and camcorders:
- Optical Technologies
- Newly developed optical materials combined with the very latest lens element design innovations and their multilayer coatings - that produce an unsurpassed pristine imaging system for the most discerning production team.
- Power Optics - speaks to the combination of specialized materials (Hi Index, Ultra Low Dispersion glass and some Fluorite elements), contemporary optical design, and multilayer coatings that produce the superb imagery (called the X-element optics):
- Virtual elimination of curvature of field and dramatically reduced chromatic aberration
- Optimization of MTF at the wide aperture settings
- Very short MOD of 45.7 inches from the image plane
- Internal Focus - a Canon design innovation that uses a three group floating optical system to better control chromatic aberrations
- Mechanical
- Common 95mm port on all of the lenses (same optical filters and matte boxes apply to all six lenses)
- Magnesium alloy body for exceptionally low weight of 5.9 lbs and rugged durability
- Dual large and luminous scales for Focus (marked in feet) and Iris facilitate precision control in low light shooting environments
- 270 degree rotation for the Focus control
- Eight-blade Iris
- Traditional film-style lens feel and operation - no mechanical play or backlash
- Unified and precision positioning of the Zoom, Focus and Iris gearing facilitate rapid and accurate lens exchanges
- Gear rings are compatible with external standard motorized control systems used for film lenses
