Nikon AF-S NIKKOR 200-400mm f/4G ED VR II Lens

 The 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. Effective for sports, wildlife, and aviation photography, this is very versatile super telephoto lens with a constant maximum aperture compatible with FX and DX format DSLRs. On DX format cameras it provides the 35mm focal length equivalence of 300-600mm.

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. When you engage the Memory Set switch you can focus on a subject and store the focused distance in the lens' memory; it stores the information even if the camera is turned off. By switching to Memory Recall the lens will automatically return to the stored focal length. For example, if you are shooting a baseball game you can pre-set the focus from the camera to second base, shoot action at another area of the field, then engage Memory Recall to quickly capture the action at second base without having to refocus.
