Nikon NIKKOR Z VR S

Yes, it is fully compatible with both. When used on an APS-C (DX) body, the crop factor will effectively extend your reach even further, providing a tighter field of view.

The integrated Vibration Reduction is highly effective, allowing you to shoot at slower shutter speeds than you typically could handheld. It is particularly useful when shooting at the 400mm end where even minor hand tremors can cause blur.

This lens is excellent for video. It uses a Stepping Motor (STM) that is designed to be fast, smooth, and virtually silent, ensuring that your autofocus adjustments aren't picked up by your camera's microphone.

The lens is weather-sealed to protect against dust and moisture, making it reliable for outdoor photography in challenging conditions. However, it is not fully waterproof, so you should still avoid direct exposure to heavy downpours or submersion.

The L-Fn buttons allow you to assign specific camera functions directly to the lens, such as AF-ON, subject tracking, or exposure lock. This lets you adjust settings quickly without taking your eye away from the viewfinder.

At 1002g, the lens is relatively lightweight for a super-telephoto, but it is still substantial. While it can be handheld, using a tripod or monopod is recommended for long sessions or when shooting in low light to maximize stability.
