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's Auto Focus extension tubes are designed with all the circuitry and mechanical coupling to maintain auto focus and TTL auto exposure.

If you don't want to spend a lot of money on macro/micro lenses, get these extension tubes. Way better than the close up filter. I do all my macro shots with these tubes on my 70-200mm f/2.4. Money well spent. $1000 for micro lens vs. $170 for extension tubes.

The product functioned well but it rattles and appears lightly constructed. It meets my needs for an occasional use item, but I don't know if I would recommend it for heavy use.

I bought these for the Nikon d60/d40, and use them with a stock 18-55mm kit lense, and a 50-200mm zoom lense. These tubes are a little snug going on and off the camera, however, that does not interfere with the working of the product. I have had these for about a month, and they do a nice job of doing what I bought them for. It should be noted that with a standard 18-55mm kit lense, and all 3 tubes, you will be right on top of the subject in order to get the focus. To get the best pictures out of extension tubes a tripod and wireless shutter remote are really a must because the slightest camera movement will completely ruin the picture. Also, Getting one pedal of a flower in focus close up just doesn't work...in order to get any depth of field, you'll have to close the apeture and cool down the shutter speed, which also makes the tripod/remote a must. Boosting the ISO can help, but if you go too far, you'll lose clarity, so you have to work the controls on the camera for best quality. Another thing to note...these are meant to work with the electronics of the Nikon, don't be fooled by the cheap price of overseas knockoffs, they have NO electronics (and usually will state such), and Nikon has no manual aperature controls, so you must have tubes made specifically to work with Nikon mount cameras to control your lense through the tubes and that means the bigger bucks...spring for it, or be severely disappointed.

Allows closer focusing, and hence larger close-ups - as promised, but the coupling is sloppy and therefore doesn't hold tightly, i.e. there is some play between the successive extension elements/camera body/lens. I dont know yet if this has a noticeable affect on image quality, but theoretically, if the lens is allowed to sag, the image is hitting the sensor at a bit of an angle, which would affect image quality. In any case its unsettling. I dont understand why the coupling cant be made as tight as a normal lens coupling. I haven't noticed an affect on focus or aperture adjustment, but if you can find a better quality coupling in an extension tube, get it, instead of the Kenko.
