About Kenko

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 off when using any extension tube, sometimes the equivalent of 3 f-stops of light is lost when using multiple extension tubes together. This light lost can affect the camera's ability to auto focus. Manual focusing is recommended should the lens begin to "hunt" (not lock onto the subject).
3. Nikon "D" information is not transmitted because the lens is focusing closer than its programmed to focus.
4. Kenko Auto Extension Tubes are not auto focus compatible with Nikon AF-s (Silent Wave) lenses, manual focusing is required with these lenses.

DG Series
New DG Series have upgraded "Gated-Array" circuitry to work better with the digital SLR's and some of the the new digital only lenses. They still work the same with film SLR Cameras and lenses as well

HORRIBLE

I called prior to ordering to ask how good these were and was told they were amazing for macro photography. It severely altered the quality of my photo. They all just looked sort of fuzzy rather than clear like all my other photos turn out. It dropped my lens off once when I was taking a photo and I had put it on correctly. These were so insanely HORRIBLE that I returned them and would NEVER recommend these to anyone for macro photography.

Great product!

By

It works advertise, I have the most success with the 50 mm. Zoom lenses will be difficult to use the AF. Prime lenses focus like normal, great product for a good price and it's a good alternative to macro lens.

Cool Product, Super Macro Photos

By

Really cool item to have in your bag of equipment that produces excellent close-up photography. Takes some time to get used to using these but once you get the hang of it...great photo results.

Inexpensive Macro option

By

Works well with my Nikon D60 and D7000. The picture quality is good. Autofocus on AFS zoom lenses is slow / unreliable - especially when the tubes are stacked. However this works much better with prime lenses.

Love it. Exactly what I need for less

By

It mounts between my Nikon D7000 and Nikon 50mm prime lens. It works perfectly. My primary use is jewelry. Love it.

Doesn't feel very solid

By

I haven't used it very much yet but it doesn't feel very solid. I bought it since Kenko extension tubes are pretty much the standard. I'm hoping they are sturdy despite my initial impression. I had a set of Vello tubes and one of them locked on to a lens and it was ruined in detaching, which I wasn't sure if I'd be able.

Kendo Aextubedgn DG Auto Extension Tube

By

I like to photograph small objects, flowers and such to bring out the small details that are usually missed in larger photos. These extension tubes are a way of doing that.

Easy to use and works great!

By

The only thing I'd want to know is you should have a spot for it in your case or get a tube for it.

Fun alternative to dedicated macro lens

By

I already own some of the best and most expensive lenses that Nikon has to offer but unfortunately none of them have macro capabilities so I have shied away from doing that kind of photography. while I replenished my budget, I decided to get the extension tubes so I can get a better feel for macro photography and to see whether I really need it and macro lens. My conclusion is that there is absolutely no substitution for a macro lens. Using these cubes is very awkward because unlike a macro lens where you have the ability to focus to infinity, when you add these tubes, you get a very narrow window of focus. This is not to be confused with the narrow depth of field which is normal for macro work. For example, if I put tubes on my 50 mm lens, I can only focus when I'm about 2 inches away from the subject. This of course creates very good magnification, but if I wanted to move further away for a slightly bigger object, it would be impossible. I have found that 130 mm is about as far as you can go with these tubes. So is it worth it? Perhaps. If I could do it over however, i would have gone with a dedicated macro lens even if it was an older version. as far as tubes go however, these work great.

Questions about this item:

JOHN K  Will they work with Nikon type G lenses and allow the aperture to be adjusted?
JOSEPH S  I have used them with the Nikkor 200mm macro which is a G lens and I can adjust the aperture. I have done it with a D700, a Df and a D3s and it worked fine
JOHN K  Thank you!
Kenita G  I have a Nikon D700. I use a 28-300 lens mostly. Will this work on my camera and do I need it for Fine Art Nature Photography?
JOHN L  It works fine on my D90, so I would expect it will work fine on a D700. It's not essential for fine art nature work - it just lets you focus closer on small subjects such as insects. Be aware you will not be able to focus to infinity when it is on the camera.
Kenita G  Thank you for your advice. I'm going to S. Texas for a photo shoot. I bet there will be plenty of creepy, crawly insects. I did order the tubes. Happy Clicking
