The incredibly powerful AF-S NIKKOR 200-400mm f/4G ED VR II Lens from Nikon is a super telephoto zoom that delivers images with superior image quality. The lens features the innovative Vibration Reduction (VRII) system that allows handheld telephoto zoom shooting even in poorly lit conditions.
There are four switches conveniently positioned on the rear of the lens barrel used to engage different focusing modes. While autofocusing, the focus can be locked by engaging the AF-L switch; the AF-ON switch allows quick autofocusing on and off.
Note: Be careful not to hold the camera body when the lens is attached, as this may cause damage to the camera. Be sure to hold both the lens and camera when carrying.
