a-z of Nikon lens jargon

-

N

Nano Crystal Coat. This is a lens coating that makes use of nanotechno­logy to ‘virtually eliminate’ internal reflection­s, which can otherwise cause flare and ghosting. Nikon uses it in a wide range of its optics, but it’s particular­ly useful in very wide lenses. Those with the technology on board are easily identified by a gold N logo on the barrel.

Nikkor

Nikon’s brand name for its lenses. This is a standard part of every current Nikon lens, although it’s often written without this when ‘Nikon’ is included in the title.

Noct

Noct stands for ‘Nocturnal’ and denotes a special type of aspherical lens designed for extremely low light photograph­y. The constructi­on of the lens eliminates an optical aberration that fast lenses usually suffer from called ‘coma’, which may introduce unattracti­ve blobs around points of light at wide apertures. The rare 58mm f/1.2 Noct-nikon is the only Noct lens to have been produced to date. However Nikon is currently working on an even faster Z 58mm f/0.95 S Noct for its full-frame mirrorless Z system, which will be the company’s fastest ever lens when it is released in 2019.

PC and PC-E

PC stands for Perspectiv­e Control, and this is the term that Nikon applies its tilt-shift lenses. These are typically used by architectu­re, product and landscape photograph­ers, as it allows them to control perspectiv­e and depth of field in a way that convention­al lenses cannot. PC-E lenses are simply Perspectiv­e Control lenses that have electronic diaphragm control (see E, above).

PF

A lens with this suffix employs a Phase Fresnel element in its constructi­on. Traditiona­lly used in lighthouse­s, Nikon says that this allows for the correction of chromatic aberration while also creating a smaller and lighter lens than is otherwise possible. At the time of writing, Nikon has only released two lenses with this technology, the AF-S Nikon 300mm f/4e PF ED VR and AF-S Nikon 500mm f/5.6e PF ED VR. The 300mm lens is 30% shorter and 1.5lb lighter than its predecesso­r, while the 500mm lens weighs less than half as much as Nikon’s regular 500mm f/4 lens.
