Advanced Autofocus technology
Canon's Advanced Autofocus technology keeps images in focus so
camera operators can concentrate on the shot. It employs a
TTL-Secondary Image Registration Phase-detection system, originally
developed for single-lens reflex still cameras, to ensure both
high-accuracy and a high tracking capability. Two autofocus
operating modes are available as well as a choice of three
positions of the AF frame in the viewfinder.
Power optics
Advanced materials (including a high index ultra low dispersion
material) combined with contemporary optical design and multilayer
coatings produce an unsurpassed imaging system, for pristine
results.
Internal Focus
Internal Focus uses a floating optical system to control chromatic
aberrations. It allows operators to achieve wide-angle with reduced
distortion and minimises variation in centre of gravity while
focusing.
Optical Shift Image Stabilizer
A second generation, built-in Optical Shift Image Stabilizer system
(Shift-IS) counteracts shake, ensuring smooth, sharp images in all
situations, whether at telephoto extremes or shooting high-speed
objects. Includes separate horizontal and vertical control with
high/low sensitivity settings.
Precision digital servo system
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.
Constant Angle Focusing System (CAFS)
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.
Robust ergonomic design
The lens is ergonomically designed to eliminate centre-of-gravity
variations with focus movement
