Nikon extension rings can be used singly or in combination to vary the reproduction ratio of lenses from 20 to 300mm. They are mounted between the camera body and the lens, As a rule, the effect becomes stronger the shorter the focal length of the lens in use, and the longer the focal length of the extension ring. Through the-lens exposure control automatically compensates for lens extension. Manual and aperture-priority auto-exposure control modes are possible. Manual focus only.

I use this product to enable many of my lenses, manual and af, to focus closer in my macro photography.
I bought this so I could mount an Arax 80mm f2.8 Tilt Shift lens on my D90 with full rotation (the flash on the camera sticks out too far). This 8mm spacer works just fine. The construction is superb. I also use other tubes for increased magnification. I also use this with AIS lenses on my D7000 and it opens up another very nice realm of macro/close focus options.
