Canon's Power Optical System is designed for unsurpassed studio
imaging with pristine results. It includes advanced materials and
multilayer coatings and delivers minimal distortion, as well as
significantly reduced ghosting and flare. Optional wide attachment
also available.
Internal Focus uses a floating optical system to control chromatic
aberrations. It allows operators to achieve wide-angle with reduced
distortion and minimises variation of the centre of gravity while
focusing.
A digital servo system uses Canon-developed 16-bit optical rotary
encoder devices to ensure precision control and repeatability of
zoom and focus settings. The system allows for digital interface to
Robotic and Virtual studio systems. 10-bit Iris Compatibility
ensures high-resolution iris control.
CAFS uses a 32-bit CPU to eliminate focus "breathing". It
calculates focus changes and synchronises the zoom to counteract
picture size/angle of view changes when focusing.
The lens is ergonomically designed to eliminate centre-of-gravity
variations with focus movement. Sealed optics offers protection
against dust and smoke, while innovative electrical sealing
techniques protect against radio interference.
All contemporary Canon lens systems are free of lead and other
substances identified as harmful to the environment.
A crossover system allows use of the associated camera to switch in
the optical extender system or change the aspect ratio between 16:9
and 4:3. 4-position turret includes spare switch positions.
