Nikon has announced the development of an AF-S Nikkor 500mm f/5.6E PF ED VR, an ultra-portable super-telephoto full-frame FX lens.
“The AF-S NIKKOR 500mm f/5.6E PF ED VR will deliver exceptional agility and optical performance in an incredibly compact and lightweight package,” Nikon says.
The portability comes thanks to Nikon’s Phase Fresnel (PF) technology, which was first launched in the 300mm f/4 PF back in 2015.
Including a Phase Fresnel element inside the lens allows it to be both light and compact — fewer lens elements are needed — while reducing chromatic aberration. The downside to using this type of element is that strong light sources can produce colorful ring-shaped flares — Nikon’s solution is a feature called “PF Flare Control” in its Capture NX-D RAW software, which helps reduce these rings.
But the benefits of Phase Fresnel technology are great: Nikon’s 300mm f/4 became the world’s lightest full-frame autofocusing 300mm lens when it was announced, and it was 52% lighter (1.66lb/0.755kg vs 3.17lb/1.44kg) and 30% shorter (5.81in/14.75cm vs 8.76in/22.25cm).
Nikon’s upcoming 500mm will have similar size and weight savings.
“Despite its 500mm focal length, the lens is small and light enough to use hand-held in a wide variety of situations where a photographer must capture unpredictable and fast-moving subjects, including sporting events and wildlife photography,” Nikon says.
Pricing and availability for the upcoming AF-S NIKKOR 500mm f/5.6E PF ED VR have yet to be announced (the 300mm f/4 PF lens costs $2,000).
