Lens Care

•Although you should always keep the lens surfaces clean, rough cleaning must be avoided. Wipe with a soft, clean cotton cloth moistened with alcohol to remove grease or fingerprints from the lens surfaces.

If you use ether in cleaning the lens, a smudge sometimes appears on the surface of a multi-coated lens. If this happens, wipe it again with a cotton cloth moistened with alcohol.

•To protect the lens surface from dirt or damage, the use of a UV filter is recom- mended at all times. The lens hood also helps to protect the lens.

•Keep the lens cap in place whenever the lens is not in use.

•Attach both the front and rear caps when the lens is stored separately.

•To ensure proper fit of the lens when stored in the leather lens case, set the lens' - focusing ring to the infinity (°°) setting.

Objektivpflege

•Wenngleich die Linsenoberflachen des Objektivs immer sauber gehalten werden sollten, mufi ein grobes Saubern vermieden werden. Reinigen Sie mit einem weichen, sauberen Baumwolltuch, das vorher mit Alkohol angefeuchtet wurde, um Fett oder Fingerabdriicke von der Glasoberflache zu entfernen. Wenn Sie zum Reinigen des Ob- jektivs Ather verwenden, erscheint manchmal ein Schmutzfleck auf der Oberflache eines multicoating-Objektivs. Wenn das einmal vorkommen sollte, noch einmal mit einem in Alkohol angefeuchteten Baumwolltuch abwischen.

•Die Frontlinse des Objektivs sollte grundsatzlich durch einen UV-Filter vor Staub und Beschadigung geschiitzt werden. Auch die Gegenlichtblende bewahrt sich als Frontlinsenschutz.

•Bei Nichtbenutzung sollte der vordere Objektivdeckel grundsatzlich aufgesetzt blei- ben.

•Wird das Objektiv ohne Kameragehause aufbewahrt, sollten vorderer und hinterer Objektivdeckel aufgesetzt sein.

•Zur Aufbewahrung im Leder-Objektivkocher den Entfernungsring auf unendlich (°°) einstellen.

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.
