The Nikon Z 600mm f/6.3 VR S follows on from a couple of other super-telephoto lenses that have really impressed us. The most similar is the Z 800mm f/6.3 VR S, which has the same kind of design, based on the use of a Phase Fresnel element in the optical path. Similar to those used to focus lighthouse beams and theatrical stage lights, this enables a smaller, more lightweight design. Even so, the Z 600mm is significantly smaller and lighter than the Z 800mm, weighing in at just 1,470g (including tripod mounting ring), compared with 2,385g. It also has a regular 95mm filter attachment thread at the front, whereas the Z 800mm takes 46mm drop-in filters at the rear.
