Nikon's revolutionary PF 300mm — Phase Fresnel element cuts weight in half vs conventional 300mm f/4.
The Nikon AF-S Nikkor 300mm f/4E PF ED VR launched in 2015 as a revolutionary telephoto prime using a Phase Fresnel (PF) element to dramatically reduce size and weight. At just 755g — roughly half the weight of conventional 300mm f/4 primes — it redefined what a fast telephoto could be.
Optically very good — the PF element enables a compact design while maintaining excellent sharpness. VR provides approximately 4.5 stops of stabilisation. AF-S motor is fast and quiet. The PF element can produce unique flare patterns in certain backlit conditions — a known characteristic.
Nikon F mount with 77mm filter thread. Just 755g — dramatically lighter than the 300mm f/4D at 1440g. E-type electromagnetic diaphragm. Full weather sealing. 1.4x TC compatible for 420mm f/5.6. Minimum focus distance 140cm.
Available used at professional prices — the weight savings maintain strong demand. The PF flare characteristic is well-documented — a ring-shaped flare in specific backlit situations. Firmware updates improved this. The Z 400mm f/4.5 VR S used similar PF technology. A game-changing telephoto.
