The PowerShot SX500 IS is equipped with Canon's latest advancements in Autofocus (AF) technology. Canon's newly developed AF achieves a significant increase in speed, for a shooting experience that's spontaneous and natural. The remarkably responsive High Speed AF lets you capture great shots as they happen, with reduced lag time.
Several engineering breakthroughs contributed to this major enhancement to speed. In addition to improved AF algorithms, the camera can process multiple sequences simultaneously, and takes advantage of reworked controls between AF and the start of shooting.
