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.
The lens features the innovative Vibration Reduction (VRII) system that allows handheld telephoto zoom shooting even in poorly lit conditions. The VRII system minimizes image blur caused by camera shake, and offers the equivalent of shooting at a shutter speed approximately three shutter speeds slower than would otherwise be possible. The lens is built with Nikon's Silent Wave Motor (SWM) which provides swift autofocusing with superior accuracy and ultra-quiet operation. And the lens can be switched quickly from AF to manual focus.
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.
This lens features a 20-elements/17-groups construction with Nikon's Nano Crystal Coat lens coating and four ED (Extra-low Dispersion) lens elements which help to yield color-corrected images with minimal distortion and aberrations. Wide zoom and focus rings enable comfortable lens control and an integrated, rotatable tripod foot is supported. With magnesium die-cast barrel construction, enhanced dust and moisture resistance and a protective meniscus front element, this lens can be confidently used in inclement weather.
