Technology

• 

  A-M

  A-M stands for Auto-Manual Mode. Thanks to a mechanism incorporated in the lens barrel, smooth focusing operation in Manual focus mode is realized in the same way as users have become accustomed to with conventional manual-focus lenses by adding an appropriate torque to the focus ring.

• 

  AS

  AS désigne les lentilles asphériques. Ce type de lentille comprend des surfaces non sphériques sur l’un ou les deux côtés du verre afin d’éliminer certains types d’aberrations.

• 

  Electromagnetic Diaphragm Mechanism

  An electromagnetic diaphragm mechanism in the lens barrel provides highly accurate electronic diaphragm or aperture blade control when using auto exposure during continuous shooting. With conventional D/G type lenses, the diaphragm blades are operated by mechanical linkage levers.

• 

  ED (Extra-Low Dispersion) Glass

  An optical glass developed by Nikon that is used with normal optical glass in telephoto lenses to obtain optimum correction of chromatic aberrations.

• 

  Revêtement en fluorine

  Les photographes ont besoin d'un équipement en mesure de résister aux éléments. Le revêtement en fluorine de Nikon repousse efficacement la poussière, les gouttelettes d'eau, la graisse ou la saleté, assurant un retrait facile même lorsqu'elles adhèrent à la surface de l'objectif. Le revêtement en fluorine de Nikon résiste à l'essuyage fréquent de la surface de l'objectif et son effet antireflet rend également les photos plus nettes.

• 

  IF Lens

  A NIKKOR lens in which only the internal lens group shifts during focusing. Thus, IF NIKKORS do not change in size during AF operation, allowing for compact, lightweight lenses capable of closer focusing distances. These lenses will be designated with the abbreviation IF on the lens barrel.

• 

  M/A

  Select NIKKOR lenses have a focusing mode which allows switching from automatic to manual focusing with virtually no lag time by simply turning the focusing ring on the lens. This makes it possible to seamlessly switch to fine manual focusing while looking through the viewfinder.

• 

  Traitement nanocristal

  Revêtement antireflet développé par Nikon, permettant d’éliminer pratiquement tous les reflets sur les éléments internes de l’objectif, sur une très large plage de longueurs d’onde.

• 

  Super Integrated Coating

  Nikon Super Integrated Coating is Nikon's term for its multilayer coating of the optical elements in NIKKOR lenses.

• 

  Silent Wave Motor

  AF-S NIKKOR lenses feature Nikon’s Silent Wave Motor (SWM). This technology converts “traveling waves” into rotational energy to focus the optics. This enables high-speed autofocusing that's extremely accurate and super quiet.
