Product Description
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 Canon 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

Extension tubes do not contain any glass/optics and are designed to enable a lens to focus closer than its normal minimum focusing distance. As such they effectively magnify your subject. The extension tubes are mounted between your lens and the camera body to create more distance between the lens and your sensor. By moving the lens further away from the camera sensor, the lens is forced to focus much closer than normal and your image is essentially cropped. The greater the length of the extension tube, the closer the lens can focus. Basically the sensor captures a smaller amount of the image with the rest of the image being outside of the sensor.
You have to take into account the focal length of your lens when applying extension tubes. For example, if you have one of the 50mm Canon primes, you cannot use the full 68mm of the extension tubes as you will never be able to focus the object.
I done a great deal of research into extension tubes and which ones to get before deciding to go with the Kenko Automatic tubes. The automatic part of the Kenko set is that each tube has a series of connectors which relay information from the camera to your lens and vice vera. Thus all the EXIF data is passed on, auto focus, aperture etc. all work just as if the lens was connected directly to your camera.
The Kenko tubes work with both APS-C and full size cameras and lenses (basically EF (Full Frame) and EF-S (APS-C) lenses).
I've tried out a variety of lenses with this Kenko set including but not limited to 18-135 EFS, 70-300EF and 100L EF Macro lens. All the lenses I have tried have worked without problem. I have even used this extension set along with a Metabones III adapter to on my Sony A7 full frame again without incident.
By giving you three separate extension tubes you have much greater flexibility in the amount of magnification you desire and working with a proper macro lens (e.g. Canon EF100L 2.8 USM Macro) you can get extremely close into a subject. You can however use these lenses to turn a non-macro lens into a sort-of macro if you don't want to spend the money specifically on a macro lens (if you are interested in macro photography you really do need a specific macro lens). For example I used these extension tubes with my 70-300mm lens to get some quite detailed and sharp images of flowers and insects.
When shooting macro, you have a very narrow depth of field and it is also harder to keep a subject in perfect focus (a tripod really is a must). Using extension magnifies these effects.
The only downside to the Kenko set of extension tubes if the price. They are well constructed, fit tightly and work very well but I still think $200 is a little much when all they really are is a set of tubes and connecters (no optics).
Overall a great addition to a macro photographers toolkit and I carry these around in my camera bag everywhere I go.
The macro + 12mm extension is a great combination, making it possible to again use the macro lens for larger subjects. Autofocus still works fine, although I don't always use it for macro, depending on what I'm photographing. The 300mm F/4 + 36mm extension is a perfect dragonfly setup for most species, allowing me to get close enough to fill the frame on larger species. Again, autofocus works fine, as does aperture (unlike with macro, where I usually use f8 or f11, I use a variety of apertures for dragonflies) I haven't yet tried stacking more than one extension tube, but expect that will allow me to get closer to damselflies and small dragonflies, while still retaining more working distance than I would get with a macro lens.
I haven't yet tried the extension tubes with my 35mm reverse macro set, but I will soon. The Kenko tubes are solid and slip on and off easily, and seem to be well-made. The one potential issue is that it is possible to bump the release lever if you're not careful. It's unlikely that the lens will fall off, but it's a good idea to be careful and aware of the possibility.
Honestly, I didn't fully understand the purpose of extension tubes before I got them, but now I wouldn't go without them. They're incredibly useful. Just be aware that they function by *reducing your working distance*. If you want to magnify more without getting closer to your subject, you want extenders/teleconverters or diopter filters, not extension tubes. If you want a large depth of field with your subject sharp all the way through...no lens or extension tubes will give you that, but you might want to google "focus stacking" (it's a physics problem). If you are ONLY planning to do reverse macro, where you lose autofocus and control the aperture via a manual aperture ring, you don't need the electronics in these and can buy much cheaper, electronics-free extension tubes.
All three of the tubes in this set cost less than one Canon branch tube. Since they do not degrade my lenses and work for the frequency I need them, they proved to be a good choice for me. If I had to use them daily I would probably go with the Canon brand name.

Die Verarbeitung ist mit der "billigen" Plastik Version nicht zu vergleichen. Stabiler, nicht ganz so wackelig und eine sehr saubere Verbindung.
Die Kontakte funktionieren 100%ig und die Kamera erkennt keine Probleme.
Aber,...
Leider hat meine Canon 50D mit EF 18-200 mit dem größten Ring so seine Probleme die Schärfe selbst einzustellen. Dies scheint aber nicht an den Ringen sondern am veränderten Abstand zum Sensor zu liegen. Die ersten beiden Ringe funktionieren fehlerfrei, wobei allerdings beim mittleren Ring leicht auch Fehlschüsse beim Scharfstellen vorkommen.
Mit manuellem (MF) Fokusieren klappt die Sache recht solide und es werde wegen der Kontakte weiter Daten von Objektiv an die Kamera übertragen.
Wie gesagt, kleine Einschränkung.
Billiger als ein hochwertiges Makro Objektiv auf alle Fälle.
