Nikon Z 800mm F/6.3 VR S Lens
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. This distinct design is made possible by the inclusion of a Phase Fresnel element, which cuts the overall weight by 50% and the length by 16% compared to the former F-mount 800mm f/5.6 lens. 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. Helping to virtually eliminate chromatic aberrations, color fringing, and comatic aberrations, this lens features three ED (extra-low dispersion) glass elements, along with one SR (short-wavelength refractive) element.
