UPDATE: Pre-orders now available.
Nikon's newest super-telephoto is another addition to its PF series of lenses that use a phase fresnel lens element in order to reduce the size and weight of what would otherwise be a much larger lens similar to more traditional fast, super-telephotos. The maximum diameter of this 500mm f/5.6E PF lens is 106mm, and it's just 237mm long. It weighs about as much as the AF-S 70-200mm f/2.8E FL ED VR lens, which is quite a feat for a lens with such reach. Most fast 500mm lenses weigh about twice that much. Naturally, this lens features Nikon's dust- and drip-resistance as well as a fluorine coat on the front element to help repel dirt and moisture (and to also make it easy to clean).
This lens features a 4-stop VR system that helps compensate for motion while shooting hand-held. Three ED elements and Nano Crystal Coating increase sharpness and control flare. And Nikon is marketing this with the new Z-series mirrorless cameras, advocating for the use of this lens and the ZTF mount adapter for a lightweight, super-telephoto package.
Finally, a new Dot Sight DF-M1 accessory to be released separately will help keep track of the intended subject, even when it "exhibits sudden movement." This new dot sight's compatibility with other lenses is unclear, but it's highly likely it will work across a range of Nikon products.
