72x Standard Field Lens
The DIGISUPER 72 xs combines long focal length with affordability. Ideal for high definition sports and entertainment event coverage, it includes powerful optics and a precision digital servo system.
Advanced materials (including a high index ultra low dispersion material) combined with contemporary optical design and multilayer coatings produce an unsurpassed imaging system, delivering pristine results.
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.
