Features

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
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.
