When using a Vibration Reduction (VR) lens on a D-SLR camera, the AF-ON button will only activate the cameras focusing and metering systems, it does not activate the lens VR function. To activate the VR function the shutter release must be used.
The AF-ON button is particularly useful for sports photographers to focus track a subject before shooting with the shutter release. Using this method restricts the time the VR system has to activate and therefore sometimes it does not have time to fully stabilise the image.
If VR stabilisation is an important consideration it is recommended to always use the shutter release to ensure that the VR system is activated during focus tracking.
