Excerpt: As soon as I got the filter I screwed it on my new Nikon VR 18-140 mm lens. It will stay there all the time to protect the lens from collecting dirt getting scratched. I like clear filter for rendering true natural color spectrum.
Excerpt: Thought about buying B+W but went with Nikon. Almost can't see the filter glass, indicative of excellent multi-coating. Purchased for Nikon 70-300mm VR zoom on a D7100. Fits perfectly, front threading fits the lens cap and it clears the lens hood. Expensive, but a lot cheaper to replace than a lens. Tip: To minimize sticking with either a new filter or new lens, tighten and loosen a few times when you first put it on.
