Nikon AF-S Nikkor 200-400mm f/4G ED VR II Specification

The Nikon AF-S Nikkor 200-400mm f/4G ED VR II is a professional-grade telephoto zoom lens designed to meet the demands of wildlife and sports photographers. It features a constant f/4 aperture throughout its zoom range, providing consistent exposure and depth of field control across all focal lengths. The lens construction includes 24 elements in 17 groups, incorporating four Extra-low Dispersion (ED) glass elements to minimize chromatic aberrations and enhance image clarity and sharpness.

The lens is equipped with Nikon's Vibration Reduction (VR) II technology, offering up to four stops of image stabilization to reduce the effects of camera shake, allowing for sharper hand-held shots in challenging lighting conditions. The Silent Wave Motor (SWM) ensures fast, accurate, and quiet autofocus performance, essential for capturing fast-moving subjects without distraction.

A Nano Crystal Coat significantly reduces ghosting and flare, ensuring high-contrast images even in backlit conditions. The lens is also sealed against dust and moisture, making it suitable for use in adverse weather conditions. The minimum focus distance is 6.6 feet, providing flexibility to capture subjects at relatively close ranges.

The lens features a nine-blade rounded diaphragm, contributing to a pleasing bokeh quality in out-of-focus areas. It is compatible with Nikon's FX-format cameras and can also be used with DX-format cameras, offering an equivalent focal length range of 300-600mm. With a robust magnesium alloy build, the lens balances durability with a manageable weight for its class, making it a reliable choice for professional photographers in need of a versatile, high-performance telephoto zoom lens.

Nikon AF-S Nikkor 200-400mm f/4G ED VR II F.A.Q.

How do I properly mount the Nikon AF-S Nikkor 200-400mm f/4G ED VR II on my camera body?

To mount the lens, align the lens mounting index on the lens with the mounting index on the camera body. Rotate the lens counter-clockwise until it clicks into place. Ensure the camera is turned off before mounting or dismounting the lens.

What maintenance steps should I follow to keep my lens in good condition?

Regularly clean the lens with a microfiber cloth and lens cleaning solution. Avoid touching the lens glass with your fingers. Store the lens in a dry, cool place, and use a lens cap to protect the glass when not in use.

How can I troubleshoot autofocus issues with the lens?

Ensure the camera and lens are set to autofocus mode. Check for any obstructions on the lens contacts. If issues persist, clean the contacts with a dry cloth and ensure the firmware is up to date.

What is the best way to use the vibration reduction feature on the lens?

Activate the VR switch on the lens to enable vibration reduction. Use the Normal mode for standard photography and the Active mode for shooting from moving vehicles. Always turn off VR when using a tripod.

How do I switch between autofocus and manual focus?

To switch to manual focus, slide the focus mode switch on the lens to M/A or M. The M/A mode allows immediate manual focus override while in autofocus mode.

What should I do if the lens hood won't attach properly?

Ensure you're aligning the hood correctly with the bayonet mount on the lens. Gently press and rotate the hood until it clicks into place. If it still doesn't attach, check for debris or damage on the hood or lens mount.

How can I check if my lens firmware is up to date?

Visit the Nikon support website and find the firmware update page for your lens model. Compare the version listed there with the version displayed in your camera's setup menu when the lens is attached.

What is the recommended way to transport the lens safely?

Use a padded lens case to protect the lens from impacts. Always attach the lens cap and hood in reverse position during transport. Avoid placing the lens in environments with high humidity or extreme temperatures.

How do I ensure sharp images at full zoom?

When shooting at 400mm, use a fast shutter speed to avoid camera shake, ideally 1/400s or faster. Stabilize the camera with a monopod or tripod for increased sharpness, and use VR if shooting handheld.

What should I do if the lens feels stiff when zooming?

Check for any external debris or damage around the zoom ring. Gently clean the area with a dry cloth. If the issue persists, consider having the lens serviced by a Nikon authorized repair center.
