(More customer reviews)If you are looking for a functional macro, for example to take pictures of individual flowers, keep in mind that these extension tubes work better on telephoto lenses for this purpose.
Use of any of these tubes on a lens with a focal length of less than 55mm (on a digital camera with an APS-C sensor, 1.5x crop) will result in a focusing distance so close you would only be able to photograph the individual stamen. For example, with the 36mm tube on a 50mm lens, I could capture a human hair from a few inches away. Even the 12mm on a 50mm lens results in an exceptionally close focusing distance (eg, photographing a small nail). However, with the 12mm tube on an 85mm lens, I can capture a flower at about 18 inches away.
The tubes are decently made. I have the light-weight plastic Nikon lenses, so not a problem for these and no flexing.

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.The extension tubes have no optics. They are mounted in between the camera body and lens to create more distance between the lens and film plane. By moving the lens father away from the film or CCD sensor in the camera, the lens is forced to focus much closer than normal. The greater the length of the extension tube, the closer the lens can focus.The KENKO AUTO EXTENSION TUBE SET contains three tubes of different length, a 12 mm, 20 mm, and 36 mm, which can be used individually or in any combination to obtain the desired magnification. Kenko also makes a UNITUBE 12 mm or 25 mm which can be purchased individually.Kenko's Auto Focus 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.Please Note;1. When using extension tubes the lens will not focus to infinity. The focus range will be greatly limited to a very close focusing distance.2. There is light fall of
