The Nikon Z 800mm f/6.3 VR S is a uniquely lightweight super-telephoto prime thanks to a Phase Fresnel element, which cuts the weight by 50% and the length by 16% compared to the F mount 800mm f/5.6 lens. The PF element also compensates for chromatic aberrations and color fringing. Here are some of the other notable features of this lens:

• A specialized high-dispersion design refracts wavelengths shorter than blue, offering very accurate color reproduction.
• A sophisticated focusing system that uses stepping motors and two separate synchronized AF drive units.
• Vibration Reduction that compensates for shake by up to 5 stops.
• Compatible with optional Z mount TC-1.4x and TC-2x teleconverters.
• Advanced weather sealing.
• Memory Set button to store focusing postion and customizable L-Fn buttons to configure subject tracking, AF lock, image playback, and more.
• Compatible with 46mm drop-in style filters (tray included, filter not included).

The Nikon Z 800mm f/6.3 VR S is a great choice for Nikon Z mount shooters who want maximum reach while still operating a relatively lightweight super-tele. It is ideal for birding and other wildlife as well as sports and stadium events.
