  AS

  AS significa elementos de lente Asféricos. Este tipo de lente utiliza superficies no esféricas en uno o ambos lados del cristal con el fin de eliminar ciertos tipos de aberración del lente.

• 

  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.

• 

  Recubrimiento de flúor

  Los fotógrafos necesitan herramientas resistentes. El recubrimiento de flúor de Nikon protege eficazmente el lente contra el polvo, el agua, la grasa y la suciedad, lo que garantiza una limpieza sencilla cuando alguno de estos elementos se adhiere a la superficie del lente. El recubrimiento de flúor de Nikon resiste a limpiezas frecuentes de la superficie del lente y su efecto antirreflejo ayuda a capturar imágenes claras.

• 

  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.

• 

  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.

• 

  Nano Crystal Coat

  An anti-reflective coating developed by Nikon that virtually eliminates internal lens element reflections across a wide range of wavelengths. Nano Crystal Coat solves ghost effects caused by red light and effectively reduces ghost and flare caused by light entering the lens diagonally.

• 

  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.
