The NIKKOR Z 800mm f/6.3 VR S, from Nikon, is a super-telephoto prime distinguished by the unique combination of one of the longest focal lengths available in a surprisingly portable package. A sophisticated mixture of technologies makes this super-telephoto a relatively sleek lens, opening up new possibilities for a focal length that was previously relegated to tripod/monopod usage. Phase Fresnel element not only compensates for chromatic aberrations and color fringing but also replaces several conventional glass elements to promote a more compact and lightweight optical layout. A modest f/6.3 maximum aperture strikes a balance between a practically bright design and lightweight construction. The SR element features a specialized high-dispersion design that refracts wavelengths shorter than blue; this helps achieve truly accurate color rendering and also aids in making the lens design more compact. Nano Crystal Coat has been applied for well-rounded anti-glare protection at all angles, helping to suppress ghosting, reflections, and flare for higher contrast and more accurate color response when working in strong lighting and backlit conditions. Multi-focus system incorporates two separate AF drive units, which are synchronized, to deliver especially fast and accurate autofocus. This system uses stepping motors, which offer impressively smooth and quiet AF performance that is well-suited to both stills and video applications. Vibration Reduction image stabilization reduces the appearance of camera shake by approximately 5 stops to better enable handheld shooting in low-light situations. Synchro VR is also supported when paired with compatible cameras featuring sensor-shift VR, which combines in-body VR with optical VR for improved results of up to 5.5 stops of compensation. The physical design focuses the center of gravity around the tripod mount for smoother, more responsive panning, especially when working atop a tripod or monopod. 

Advanced weather sealing includes rubber gaskets to prevent dust and moisture ingress, the lens body is made from durable, lightweight magnesium alloy, and the exposed elements have a fluorine coating that repels dirt and oils and is easier to clean. Two customizable L-Fn buttons can be set to configure subject tracking, AF lock, image playback, or other modes. The L-Fn2 button is also accessible from four different locations on the barrel for easy reach. A programmable Control Ring can also be used to control aperture, ISO, or exposure compensation.
