Instant AF

It is vital to achieve and maintain very sharp focus when shooting in High Definition. To assist in this goal, the HR10 camcorder features Canon's revolutionary Instant AF auto focus system. It offers a dramatic improvement in auto focus speed and accuracy (compared to traditional auto focus systems). Instant AF significantly decreases the time it takes to find focus -- even in low light conditions -- and improves the camcorder's ability to maintain focus.
The hybrid control system of Instant AF includes an external AF sensor to measure the distance to the subject and an internal AF sensor to fine-tune the focus. A change in the contrast of the subject can sometimes lead to a loss of focus, even though the subject has not moved. With Instant AF, the external sensor "sees" that the subject has not moved. Focus is not lost, and your HD image remains sharp.
The benefits of Instant AF are especially apparent in high brightness and night situations. In any situation, even when following a moving subject, it's possible to achieve fast, accurate focusing.
