The AF Extension Tube Set is designed specifically for use with Nikon digital SLR cameras, can transform your Lens into a Macro Lens. It moves the lens from the film or digital sensor. The closer the focus is, the greater the magnification. The extension tube does not affect image quality as there is no optics inside. In comparison, a close up filter is often blamed for degrading the quality of image.
This tube set contains three piece tubes of different length — 12mm, 20mm, and 36 mm — which can be used individually or in any combination to obtain the desired magnification. These extension tubes are designed with all the circuitry and mechanical coupling to maintain auto focus and TTL auto exposure with most Nikon lenses, given there is enough light to activate the cameras AF system properly.
Compatible with all Nikon SLR cameras

Autofocus Macro Extension Tube Set for Nikon (Metal)
Extension tubes are designed to enable a lens to focus closer than its normal set minimum focusing distance. Getting closer has the effect of magnifying your subject (making it appear larger in the viewfinder and in your pictures). They are exceptionally useful for macro photography, enabling you to convert almost any lens into a macro lens at a fraction of the cost while maintaining its original optical quality.
