A critical objective when shooting in high definition is achieving the sharpest focus possible. The VIXIA HF G10 camcorder features Canon's revolutionary Instant AF focusing system which offers a dramatic improvement in auto focus speed and accuracy, compared to traditional auto focus systems. The Instant AF feature uses an external sensor, in combination with Canon's auto focus system, to help significantly decrease the time it takes to find focus, even in low light conditions. This system achieves focus instantaneously, reducing focus "hunting." This is especially beneficial in high brightness or night shooting situations. In addition, with Instant AF it's possible to capture fast, accurate focusing even when following a moving subject.
For those situations in which the super quick action of Instant AF might not be desirable, you also have the option of Medium AF, which is softer and smoother than Instant AF, but faster than would be possible with manual focusing.
