Detailed explanation of Nikon lens logo

Lead: The lens logo is a lens ID card. A complete logo can represent all aspects of a shot. For those lenses with the same focal length and aperture, different logos indicate different identities.

Through lens identification, we can know the interface, positioning, special lens, focus motor, anti-shake and so on of a lens. Because different brands use some special logos, you can also see which brand this lens is.

Nikon lens logo AI: automatic indexing, automatic maximum aperture transfer technology. Published in 1977, used for manual lens. Logo does not appear in the lens name, and the smallest number on the aperture ring of AI lens is green.

Ai-s: automatic indexing shutter, automatic shutter indexing transfer technology. Published in 198 1 for manual lens. There is no logo in the lens name, and the smallest number on the aperture ring of AI-S lens is yellow.

Autofocus: autofocus, autofocus technology. The AF in the name indicates that this is an autofocus lens, but the lens itself has no motor. If the body does not have a focus motor, it cannot focus automatically.

AF-I: 1992 lens has built-in motor and CPU contacts, which are mainly used for professional telephoto lenses. Has been replaced by af-S.

AF-S: autofocus lens with built-in SWM ultrasonic motor. This kind of lens can also achieve autofocus on low-end cameras such as Nikon D5 100/D3 100 without a body motor.

Asp: aspheric surface, which means aspheric lens is used in the lens.

Close-range correction system. The system enables photographers to obtain excellent image quality when shooting at close range and increasing the focus range.

D: Distance and focal length data transmission technology. D-lens supports 3D matrix photometry.

DC: defocus-image control, defocus image control. Nikon original lens can provide unique zoom control function. Its main feature is that it allows fuzzy control of the foreground or background of a specific object to obtain better defocus imaging.

DX: Special lens for APS-C camera, with small image field design, can't be used on Quan Huafu fuselage.

ED: ultra-low dispersion, which means that the lens adopts ultra-low dispersion lens.

G: G lens cancels the traditional manual aperture ring. G lens often appears on Nikon's latest lens together with AF-S, showing an upgrading trend.

IF: internal focusing, internal focusing technology. This kind of lens won't rotate when focusing.

Macro: Macro lens.

N: It was once used to represent new lenses, but now the N with a hollow hexagonal bottom on the lens indicates that the lens is coated with nanocrystalline.

PC-Shift: move the lens.

RF: Back focusing, back focusing technology.

S: slim and light. Appears on some thin lenses.

SIC: super integrated coating, super composite coating.

Tc: remote control converter, rangefinder.

VR: Vibration reduction and image stabilization system. This shows that the lens has anti-shake function.
