In Nikon's extensive range of Nikkor F-mount lenses for its DSLRs, a 'gold ring' towards the front of the lens barrel signifies lenses of the finest optical quality and upmarket construction. But with the advent of the Z-mount for mirrorless cameras, a simple 'S' tagged at the end of the lens name is the only indicator of top-notch glass.
That's all changed with the advent of Nikon's Arcrest II Gold Edition filters, which give your lenses the classic Gold Ring look when screwed onto the front – while also protecting your precious glass from the worst that the world can throw at it.
