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.

• 

  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.

• 

  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.

• 

  Fluorite Lens Element

  Fluorite (FL), a lightweight mono-crystal optical material, has excellent optical properties while reducing overall lens weight to improve balance and handling, especially useful in longer focal length lenses.

• 

  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.

• 

  HRI

  HRI stands for High Refractive Index Lens. With a refractive index of more than 2.0, one HRI lens can offer effects equivalent to those obtained with several normal glass elements and can compensate for both field curvature and spherical aberrations. Therefore, HRI lenses achieve great optical performance in an even more compact body.

• 

  Objectif IF

  Un objectif NIKKOR doté d'un système interne de mise au point : Seuls les groupes de lentilles se déplacent sans allonger l'objectif. Ce type d’objectifs est désigné par l’abréviation IF située sur le canon.

• 

  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.

• 

  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.

• 

  Super Integrated Coating

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

• 

  Vibration Reduction

  A Nikon in-lens technology that improves image stability by automatically compensating for camera shake. Lenses that offer VR will feature the abbreviation VR on the lens barrel.
