Newly developed materials (including the high index ultra low dispersion material) combined with the very latest in element design innovations and multilayer coatings produce an unsurpassed pristine imaging system for the most discerning production team. The HD xs logo identifies the deployment of all of these technologies in the lens.<br/> <br/> <br/> Power Optics - speaks to the combination of specialized materials, contemporary optical design, and multilayer coatings that produce the superb imagery Internal Focus - a Canon design innovation that uses a floating optical system to control chromatic aberrations Crossover Technology - switchable operation between 16:9 and 4:3 aspect ratio imagery 4-position Turret
Second-generation precision digital servo systems using Canon-developed 16-bit optical rotary encoder devices <br/> <br/> <br/> <br/> Ensures high precision and repeatability of the Zoom and Focus settings Encoders report to the 32-bit CPU - which, in turn, calculates during the focusing actuation to tightly control a synchronized zoom counter action that eliminates focus &#34;breathing&#34; (undesired change of angle of view that can accompany focus changes). This Constant Angle Focusing System is identified by the CAFS logo 16-bit optical rotary encoder for aperture control reports to the associated camera Iris control system (10-bit compatibility) 16-bit encoders are output on a special 20-pin connector for direct digital interface to Robotic and Virtual studio systems Facilitates a wide range of customized control characteristics and automatic recall of precision control settings when used in conjunction with Canon digital controllers for Zoom and Focus
Ergonomic mechanical design that exploited Power Optic technologies to maintain the same size and weight as the predecessor SDTV studio lens: Effective elimination of center of gravity variations with focus movement (using Canon&#39;s advanced 3 group Internal Focusing system) Further empowers the creativity of the camera operator Protection against dust, smoke, and other air-contaminants Protection against radio interference
