Nikon just announced that it is developing a 500mm f/5.6 lens with a Phase Fresnel element, which would make it only the second lens in Nikon’s lineup to have such a specialized component, the other being the 300mm f/4 PF. This indicates that Nikon is prioritizing low weight for the 500mm f/5.6, given that a PF element can replace multiple standard lens elements with one that is much smaller and thinner. No price, shipping date, or photos of the new lens have been released. The full name is the AF-S NIKKOR 500mm f/5.6E PF ED VR.
