A bright off-axis non-incicent beam of light, such as from the sun in the corner of a frame, can still create large, bright, and very detrimental flare, ghosting, and contrast reduction even on a lens with multicoating. Also in this type of coating (invisible) hairline cracks can occur due to the “working” of hot or cold materials. Marble Nano Crystal Plating Agent】Our PH balanced formula will keep your stone sealed from deterioration and keep your stone shining for a long time.
The anti-reflective coating is designed to be exactly as thick as half the wavelength of the frequency of light. I say, "I suspect," however, because isolating it as a factor in Nikkor-per-Nikkor comparisons is near impossible: there aren't any Nikkors (that I know of? However for the normal micro contrast and detail I think it's improvements in the optics in general that seem to make more of a difference. If it’s regularly used, the extra level of protection will keep your furniture looking newer longer. Is this just a completely crazy, impossible line of questioning that I should forget, given that I clearly have more important things to learn about technique and aesthetics that would make far more difference to the quality of my work?
Since it's applied to only one surface of one element, there must be one "critical" element whose surface reflections contribute significantly to flare, otherwise it will have little effect. Do not touch the water within 24 hours after crystal plating, natural air drying can be kept transparent and bright. G. Wood and Voigtlander lenses will still be going strong, while my state of art Nikon lenses are unusuable. As they become cheaper and more commercially available, use of nano coatings is becoming far more widespread. br />
While he seemed to really know what he was talking about when it came to gear, including all kinds of different cameras, one point that really surprised me is that he said every lens should have a protective filter on it.
The particular make up of these nano-particles keeps them all flat and uniform, which causes the surface to become incredibly smooth at a microscopic level. Inert and breathable, nano coatings are safe to use on any building quality stone, including marble, so don’t worry about damage.The claim to improved sharpness is more likely due to more freedom in lens design, and the ability to utilize more lens elements a lens designer might otherwise be limited to due to transmission requirements. I think the term Nikon should have used is "hydrocarbon solvents", like xylene, acetone, MEK, naptha, etc.
Granted, that is far lower than the 8-10% that used to exist with single coating and uncoated lenses, however in complex lenses with many elements, a considerable amount of light can still be lost overall (i. e. a complex 15 group telephoto lens could end up with 15-30% loss in total transmission in the face of strong flare.
That said, the more I work with nano-coated lenses alongside others in my collection, the more I've begun to notice that the nano-coated variants seem to have a special "sparkle" with detail.
