The KJ17ex7.7B and the HDgc line of lens have been specifically designed for low cost acquisition and this lens is particularly well suited to reality TV, newsgathering and other low budget HD productions.
The KJ17ex7.7B’s short 7.7 mm focal length translates to a 63.9 degree horizontal angle of view for the 16:9 HD image format. Combined with a focal range that has been extended to now cover a range from 7.7mm to 131mm (and 262mm with extender) this lens offers unsurpassed operational capabilities in a compact package weighing less than 1.62kg. Focus breathing is significantly reduced. The maximum relative aperture is F1.9 which, combined with the typically F-10/11 sensitivity specifications of the contemporary HD ENG cameras, ensures excellent video pictures in very low light environments.
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.
A Canon design innovation that uses a floating optical system to better control chromatic aberrations
Enhanced servo system called Shuttle Shot that adds value-added creativity to handheld acquisition systems
Advanced Drive technology
Encompasses servo control that allows the operator to precisely zoom between tow pre-programmed zoom positions Maximum Zoom speed is 1.2 seconds over entire range
