Nikon 200-400mm f4 G VR II AF-S ED Lens

VR II allows you to shoot handheld at shutter speeds up to four stops slower than you normally could without introducing camera shake, resulting in sharper images in a wider range of lighting conditions and shooting situations.

The Nano Crystal Coat significantly reduces internal reflections, thereby minimizing ghosting and flare. This leads to clearer, sharper images with improved contrast, especially when shooting into bright light sources.

Yes, the lens features a tough magnesium alloy body with weather sealing designed to withstand dust and moisture, making it reliable for use in challenging environmental conditions.

It features Nikon's Silent Wave Motor (SWM), which provides exceptionally fast, smooth, and quiet autofocus. The addition of the new A/M mode also offers enhanced control during shooting.

This lens is ideal for professional photographers specializing in wildlife, sports, and action photography who require significant reach, exceptional image quality, and reliable performance in demanding situations.

While specific compatibility depends on the teleconverter and camera body, Nikon's professional lenses are generally designed to work with compatible Nikon teleconverters, though autofocus performance may be affected.

Yes, like most professional f/4 super-telephoto zooms, it is substantial in size and weight. For critical sharpness, especially at slower shutter speeds or during long shooting sessions, a sturdy tripod or monopod is highly recommended.

Ensure the focus limiter switch (if applicable) is set correctly. Check that the camera's autofocus mode is appropriate for the subject. Clean the electrical contacts on both the lens and camera body. Ensure sufficient light is available for the AF system.

Verify that VR II is enabled (if desired). Ensure the shutter speed is appropriate for the focal length and subject motion. Check that the focus point is accurately on the subject. If using a tripod, ensure it's stable and VR is set to 'off' or 'tripod mode' if available.

Ensure the lens is securely attached to the camera body. Clean the electrical contacts on both the lens and camera. Try reseating the lens. Test with another lens to confirm if the issue is with the camera or the lens.

Ensure the lens hood is properly attached. Adjust shooting angle to avoid direct light sources entering the front element. Clean the front lens element as dust can contribute to flare.
