A 400mm F2.8 lens is the industry standard for sports photography and is often used with a teleconverter. The Nikkor Z 400mm F2.8 TC VR S is the first of its type to sport a built-in 1.4x teleconverter, which is activated using a conveniently located switch. This allows photographers to quickly increase the focal length to 560mm. Despite this, the lens is 20% lighter than its F-mount predecessor. As can be expected from a lens built for professional use, this versatile telephoto lens offers high build quality, quick autofocus and excellent optical performance.
