What is Nano Crystal coat?
Nano Crystal Coat is a revolutionary technology that dramatically reduces ghosting and flare and results in sharper, clearer, high contrast photos and videos. This low-refractive coating is comprised of microscopic nano particles and is far more effective than conventional anti-reflection coating systems.
What is Nano coating for camera lens?
With this in mind, Nano Crystal Coat that consists of nanometer-sized* particles is applied to the surface of a lens. This reduces the difference in refractive index between the glass and air by creating a structure that has spaces between one particle and another.
What does SWM mean on Nikon lens?
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.
What is CRC lens?
The Close-Range Correction (CRC) system is one of Nikon’s most important focusing innovations, for it provides superior picture quality at close focusing distances and increases the focusing range. The CRC system is used in fisheye, wideangle, Micro, and selected medium telephoto NIKKOR lenses.
How is nano crystal coat used in lenses?
Nano Crystal Coat is an anti reflective coating that originated in the development of NSR-series (Nikon Step and Repeat) semiconductor manufacturing devices. It virtually eliminates internal lens element reflections across a wide range of wavelengths, and is particularly effective in reducing ghost and flare peculiar to ultra-wideangle lenses.
What does Nikon exclusive multilayer lens coating do?
Nikon’s exclusive multilayer lens coating achieves high transmittance in a wider wavelength range. Even for zoom lenses with a large number of glass elements, this coating system effectively reduces the ghost and flare effects that are likely to occur in backlit situations, helping you achieve high-contrast images with rich gradation.
Why do Nikon lenses have a Fluorine coating?
Thanks to Nikon’s original technology, it delivers higher durability and is more peel-resistant. Compared to other manufacturers’ coating of a similar kind, fluorine coat endures a higher frequency of lens surface wiping and provides longer-duration staying power.
How does the if system work on a Nikkor?
The IF system is featured in many Nikkor macro, telephoto and selected Nikkor zoom lenses. With Nikon’s Rear Focusing (RF) system, all the lens elements are divided into specific lens groups, with only the rear lens group moving for focusing. This makes autofocusing operation smoother and faster.
