A critical objective when shooting in high definition is achieving the sharpest focus possible. The VIXIA HF M40 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.
To further enhance focusing capability the VIXIA HF M40 also features Focus Assist. This helps in capturing your subject in razor-sharp focus. It works by providing a 2x magnification of your subject, which is automatically cancelled when you start recording. This is a feature normally found in professional broadcast-quality cameras.
