Soins a Apporter a Votre Objectif

•II est necessaire de conserver les surfaces des lentilles de l'objeetif dans un etat de proprete maximum. Pour le nettoyage, il est recommande d'utiliser un tissu de coton doux, imbibe d'alcool afin d'effacer des traces de graisse ou de doigts. Lors- que, Ton utilise de Tether, des traces peuvent subsister apres evaporation sur une lentille qui a subi le traitement multi-couches. Dans un tel cas, frotter a nouveau avec du coton imbibe d'alcool.

•Laisser un filtre UV monte en permanence constitue une bonne protection de la lentille avant contre la poussiere et les chocs. Le bouchon avant est egalement une protection efficace de la lentille avant.

•Bouchez Tavant de votre objectif lorsque vous ne vous servez pas de votre appareil.

•Lorsque votre objectif n'est pas monte, mettez-lui ses bouchons avant et arriere.

•Pour ranger convenablement l'objeetif dans son etui en cuir, mettez la bague de mise au point sur l'infini (°°).

Cuidado del Objetivo

•Si bien siempre se debe mantener limpia la superficie del objetivo, debe evitarse una limpieza tosca. Limpie frontando con un pafio de algodon limpio humedecido en alcohol cuando deba quitar manchas con grasa o impresiones digitales de la superficie del objetivo.

Si se utiliza eter para limpiar el objetivo, puede aparecer a veces una mancha sobre la superficie del objetivo recubierto de capas multiples. Si esto sucede, limpielo nueva- mente con un pano de algodon humedecido con alcohol.

•Usar un cepillo suave-nunca tela o tejido-para quitar el polvo, las manchas per- sistentes han de ser lavadas con un tejido especial para objetivos humedecido con alcohol o lfquido limpiador.

•Para proteger la superficie del objetivo de polvo o perjuicio alguno se recomienda el uso de un filtro UV en todo momento.

El parasol tambien ayuda a proteger el objetivo.

•Dejar la tapa puesta siempre que no se use el objetivo.

•Poner ambas tapas la delantera y la trasera al guardar el objetivo por separado.

ED specifications

Nikon ED (Extra-low Dispersion) optics represent a significant advancement in lens technology, specifically designed to enhance image quality by reducing chromatic aberration and improving color accuracy. These specialized glass elements are utilized in various Nikon products, including cameras, binoculars, and telescopes, making them a cornerstone of Nikon's optical engineering.

One of the primary features of Nikon ED glass is its ability to minimize the dispersion of light as it passes through the lens. Traditional glass can produce various wavelengths of light at slightly different focal points, leading to color fringing and a loss of sharpness in photographs. By incorporating ED glass, Nikon lenses achieve better focus across the color spectrum, resulting in more precise, vibrant images with greater detail.

The use of Nikon ED glass also enhances contrast and brightness. The superior optical properties of ED elements allow for increased light transmission, ensuring that images maintain their vibrancy even in challenging lighting conditions. This capability is particularly beneficial for wildlife and landscape photographers who often work in varied environments.

Another hallmark of Nikon ED technology is its durability. Lenses equipped with ED glass are typically constructed with robust materials, making them resistant to the rigors of outdoor use. Weather-sealed designs further protect against elements such as dust and moisture, ensuring reliable performance in a wide range of conditions.

In addition to its optical benefits, Nikon ED technology also incorporates advanced coatings, such as anti-reflective coatings, to reduce lens flare and ghosting. This enhancement allows for clearer, more defined images, particularly when shooting in backlit or high-contrast situations.

Nikon's commitment to precision engineering is evident in the meticulous design and manufacturing processes involved in creating ED lenses. Each lens is crafted with stringent quality control measures, ensuring that every product meets Nikon's high standards for performance and reliability.

In summary, Nikon ED technology exemplifies the brand's dedication to delivering superior optical performance. With its unique ability to counteract chromatic aberration, enhance light transmission, and withstand various environmental conditions, Nikon ED lenses are a preferred choice for photographers seeking unparalleled image quality and durability in their optical equipment.
