The enormous picture detail captured by high definition video is extremely unforgiving of anything but precise focus. Helping camera operators to achieve exact focus each and every time at telephoto distances is the job of Canon's revolutionary new DIGISUPER 100AF and DIGISUPER 86AF long-field lenses. Both use the Secondary Imaging Phase Difference Method (see chart on the features page) of auto-focus technology, which is significantly more advanced than that used in any other high-definition broadcast zoom lens.
Based on the most widely used lenses in HD sports and entertainment production worldwide, the high-definition auto-focus DIGISUPER 100AF and DIGISUPER 86AF are designed to assist camera operators to instantly achieve exact focus at all times, which is absolutely critical in all applications of HDTV production. The auto-focus features of these lenses are not intended to do the camera operator's job for him/her, but to provide a high-tech tool to assist the camera operator in achieving exact focus each and every time, especially in challenging situations.
The DIGISUPER 100AF and DIGISUPER 86AF provide an adjustable window in the viewfinder that enables camera operators to target the object they wish to auto-focus on. The DIGISUPER 100AF and DIGISUPER 86AF feature three optional auto-focus modes: Part-Time, which auto-focuses as long as a button is depressed for quick focus confirmation or instant on-demand follow-focus; Full-Time, for situations such as shooting racing cars, where objects are speeding toward the camera position at high speed, or for situations where full-servo robotic operation is needed; and Off, for normal, unassisted lens focus operation.
Canon's DIGISUPER 100AF and DIGISUPER 86AF lenses feature the HD optical precision and heightened long-range zoom capabilities that have made Canon a symbol of excellence in sports and entertainment production. All of Canon's DIGISUPER field lenses feature Canon's unique XS technology for improved optical performance and lighter weight. All DIGISUPER field lenses 75x and higher come equipped with Canon's built-in Optical Image Stabilizer, or "Shift-IS" system, which enables directors to capture dramatic, high-impact long shots and deliver them shake-free to viewers in stunning HDTV.
The DIGISUPER 100AF and DIGISUPER 86AF lenses are Canon's latest advancements designed to provide camera operators with the industry's most sophisticated tools for success in capturing HDTV images of the world's most exciting moments.
