Kenko Auto Extension Tube Set


Used all combinations of these three tubes, excellant value for money. I don't think autofocusing is the weakness since, at such very minute object & high DOF it becomes difficult.

Value for money & you can have mulitple options of the combinations of the tubes.

Kenko Auto Extension Tube Set


excellent value for money, very solid and easy to use with autofocusing and TTL capability. (better to have f2.8 or better) work best with standard 50mm lens and you can really stop down to make some DOF. (very economical way to step into macro...

simple, solid and no lens elements high mag. ratio much cheaper than a 100mm macro lens works well with TTL flash and autofocus

autofocus failed to work on normal zoom lens with aperture smaller than f2.8 on the 26mm tube (aperture by a factor of 3x). I found it quite interesting using normal 28-70 zoom with these tubes, but prime lens are best

If you want excellent macro photography without paying ridiculous prices for a "pro-macro lens" that STILL have a minimum focusing distance, then go for this extension kit - absolutely indispensable. One note however, when using a zoom lens with these,...

Makes any lens capable of macro photography. There is NO distortion due to no glass elements (it's just a hollow tube). With the correct combination, you can get your subject focused, even when it's right up against the glass of your lens! There is no...

Makes for slow autofocus, but in macro photography, you aren't exactly chasing down race horses. This makes for a very slight weakness.

There is always some crack sound, when I use all the three tubes with my 80-200 f/2.8.You have to pay extreme attention because it is easy to break when using with a +1kg lens. So, buyers should try to get the most solid one among the other brands. Try...

AF focus ; light weight ; Interchangeable for choice of magnification and ease of use ; works well with my F80 and TTL lens

expensive for a no optic tube ; so so construction

I like the versatility of the extension tubes. Light weight and inexpensive for travel. Read and understand the light loss effects if you manually meter your subjects.

Exellent sharpness is obtained since no additional glass is in the optical path

must be careful when metering if not using your TTL functions.

A very low cost way of experiencing the beauty of macro photography.

versatility with a set of three, quality of image depends solely on lens used, and low cost

Kenko Auto Extension Tube Set


excellent for close-up/macro photography with 1:1 or more magnification. Electronic contacts work well with my Minolta AF and TTL meter.

Interchangeable for choice of magnification and ease of use.

feels like a set of rolled tin cans otherwise will do its job

Kenko Auto Extension Tube Set


extremely useful when out in the field and you need 2 get closer 2 your subject...they even link the electronic contacts between the lens and the body...just a bit pricy (but all photographic equipment seems 2 be expensive) also when used with a heavy...

very handy...fits on every lens (especially nice when used on your tele lens)

sometimes the system that hooks on the meter of the body doesn't 'lock'

Product Specifications

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.
