ED glass – essential element for Nikkor telephotos
Nikon has developed ED glass (extra low dispersion) with the aim to enable producing lenses with first-class sharpness and colour correction by minimising the chromatic aberration. Simply put, chromatic aberration is a kind of image and color dispersion that occurs when light beams of different wave lengths move through optical glass. In the past, special optical elements for telephotos, showing anomalous dispersion characteristics, especially calcium fluoride crystals, were necessary to correct this problem. Fluoride is relatively instable and reacts to temperature fluctuations, which can, by changing the refractive index of the lens, have negative effects on the focus. Therefore the developers and engineers at Nikon have developed ED glass which has all advantages but none of the disadvantages of calcium fluoride based glass. As a result of this innovation Nikon has developed several kinds of ED glass for different lenses. They are characterised by astonishing sharpness and outstanding contrast, even at highest focal lengths. Therefore Nikkon lenses of the ED series prove the outstanding relevance of Nikon in terms of innovation and increase of performance of lenses.
Aspheric lenses
In 1968, Nikon has introduced the first photo lens with aspheric lenses. But what makes them so special? Aspheric lenses eliminate the problem of asymmetry and other lens aberrations, even at highest apertures. It is especially useful to correct distortion when working with wide angle lenses Moreover, using aspheric lenses enable a lighter and smaller lens design. Nikon uses three different kinds of lenses. Precision ground, aspheric lenses are the finest expression of the high art of manufacturing lenses and place great demands on the manufacturing process. Glass plastic lenses are made of special plastic, moulded on optical glass Moulded aspherical glass lenses are made in a special metal die-casting.
Distance information
Nikkor lenses of type D and G transmit the measured distance between camera and object to the AF Nikon camera housing. This, in turn enables the use of additional functions like 3D matrix measurements and 3D multisensory fill-in flash.
Silent Wave Motor
The AF-S technology is yet another reason why many professional photographers love Nikkor telephotos. AF-S lenses use the silent wave motor by Nikon which converts “wandering waves” in rotation energy for optical focusing. This enables smooth and extremely precise and fast focusing.
Nikon Super Integrated Coating for extraordinary performances?
To improve the performance of their optical lens elements, Nikon uses a special lens multi-coating to reduce ghosting and backlight reflexes to occasional exceptions. With the Super Integrated Coating by Nikon, a whole range of goals can be achieved, like lessened reflection in a larger wavelength range, outstanding colour balance as well as high quality colour rendering even with zoom Nikkor lenses with many lenses. Due to this coating, scattered light and backlight reflexes that are caused by internal reflections by image sensors of digital Nikon SLRs are minimised. Furthermore, the process of simultaneously applying multiple layers has been especially adjusted to the design of every single lens. The number of coatings for every single lens element depends on the kind of lens and the glass used and is calculated carefully to ensure a characteristic, even colour balance for every Nikkor lens. This results in lenses whose quality is unrivalled in their industry.
DX-Nikkor Lenses
The compact and lightweight DX Nikkor lenses with smaller image circle have been designed and optimised especially for the D2-Series, D1-Series, D200, D100, D90, D80, D70s/D70, D50 and D40X/D40 of digital Nikon SLRs. They give ideal options for pictures of landscapes and other?large motives with digital Nikon SLRs in DX format.?
