Focusing
Canon RP features both Contrast Detection and Phase Detection autofocus (AF) systems which ensures speed and accuracy of focusing in most situations. The AF system has 4779 points to choose from. Canon RP also features
Face detection AF where it intelligently detects the faces in the frame and locks the focus automatically. In addition to the face detect AF, EOS RP has a more sophisticated feature called
Eye Tracking AF which detects and locks focus to the selected eye of the person in the frame accurately and tracks as the subject moves. Eye tracking AF of Canon RP is a perfect feature for shooting portraits and is especially useful when fast lenses are used and the depth of field is very narrow.
