What is Phase Fresnel?
The PF (Phase Fresnel) lens, developed by Nikon, effectively compensates chromatic aberration, utilizing the photo diffraction phenomenon*. It provides superior chromatic aberration compensation performance when combined with a normal glass lens.
What does PF stand for on a Nikon lens?

What is the difference between the canon 300mm f/4 AF and 300mm AF-S?
The 300mm f/4 AF (1987 – 2000) has even better optics, and adds autofocus. It is built like a tank, and has slow autofocus speed to match. You have to move two switches to get from auto to manual focus. The 300mm f/4 AF-S adds ultra fast autofocus with instant manual focus override.
How to use the 300mm f/4 AF-S with manual focus?
You have to move two switches to get from auto to manual focus. The 300mm f/4 AF-S adds ultra fast autofocus with instant manual focus override. The 300mm f/4 PF uses a Fresnel element for less weight. It’s the same idea as Canon’s DO lenses, which also use Fresnel elements.
What is the difference between the ED-IF and the 300mm f/4 AF?
The ED-IF adds internal focussing, and in doing that, made the lens the smallest and lightest 300mm yet, and let it focus much closer. Better, instead of the whole lens having to rack in and out to focus, all you do is flick a small focus ring. The 300mm f/4 AF (1987 – 2000) has even better optics, and adds autofocus.
Why is the Nikon 300mm not more popular?
Its optics are far superior to to previous NIKKOR-P. The 300mm f/4.5 ED added ED glass for supposed reduction in secondary chromatic aberration, but since the earlier lenses were so good, it doesn’t make that much of an improvement. Thus this lens wasn’t very popular; it cost more than the earlier version but didn’t do much different.
