  • 1Description

The Auto Extension Tube Set DG for Micro Four Thirds Lenses by Kenko is a set of two extension tubes for mirrorless interchangeable lens cameras. This set has tubes of 10 mm and 16mm. The tubes can be used individually or in combination to obtain the desired magnification.

Extension tubes are hollow cylinders without optics designed to enable a camera's lens to focus closer than its minimum focusing distance and therefore provide more magnification. They are placed between the lens and body and are particularly useful in allowing lenses without macro capability to shoot macro, but in general, they offer increased magnification for whatever need. 

An extension tube increases lens magnification by an amount equal to the extension distance divided by the lens focal length. For example, adding a 25 mm extension tube to a 50 mm lens will give a magnification gain of 0.5X. Therefore, if the lens's original magnification was 0.15X, then the new magnification will be 0.15X+0.5X=0.65X.

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

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).

    Kenko A-EXTUBEDG-M43 reviews

    Auto Extension Tube Set DG for Micro Four Thirds Lenses is rated 4.8 out of 5 by 25.
    Rated 5 out of 5 by from Excellent Tubes set for 4:3 cameras I am using these tubes set with my Panasonic GX1 in my first approach to macro photography. I have the Lumix GX Vario PZ 14-42mm lens (pancake), which features electric powered-zoom and focus operation. Both works just fine with these tubes and I have not experienced any issues using them. They are very well built and justify their price vs. cheaper / lower quality alternatives. I am still learning as I use them but have tried them separately and combined and so far I am very satisfied with the quality of the pictures obtained.

    Rated 5 out of 5 by from Increase in magnification and retains AF A great addition to the Oly 60mm macro lens. It further increases your magnification witout adding any extra lens elements that could result in a less sharp picture. All AF and lens functions are maintained. An excellent macro tool.

    Rated 5 out of 5 by from Great addition to macro lens I found that I really enjoy using the extension tubes for very close macro work. I'm quite pleased with the results I have had so far. The working distance is quite close to the subject, which I'll need to get used to but overall great product. I've had multiple people tell me I need to submit my photos to websites or create my own portfolio and try to sell eventually. That is quite reassuring as I am an amateur photographer. Thanks

    Rated 5 out of 5 by from Works with Panasonic Lumix DMC-GX8 body+ Leica 42.5 mm lens Well constructed metal coupling + electronic contacts work well with my Leica 42.5 mm portarit lens and Panasonic Lumix DMC-GX8 body. This combination allowed me to take macro photography images without buying a separate dedicated macro lens. After borrowing the Panasonic macro lens from a friend to compare images, my opinion is that using a Leica 42.5 mm lens with Kenko extension tubes achieved extremely sharp results.

    Rated 5 out of 5 by from Very well made. These are great tubes and the autofocus works. I am very satisfied with these tubes. They are a little on the expensive side however.

    Rated 5 out of 5 by from I recommend this product I use this on my Olympus E-m5, and they have worked exceptionally well. Autofocus is smooth (although I do manually focus most of the time) and they are easy to carry around.

    Rated 5 out of 5 by from A good product at a good price. I bought this set to use with my Olympus 12-40mm lens for super close up shots, using the new in-camera focus stacking feature in my Olympus E-M1. These adapters are well made and work really well, as they allow all of the auto features of the camera and lens to work. For the price, this is an excellent product.

    Rated 5 out of 5 by from Excellent Product I am using these on Panasonic Lumix DMC-G3 with Panasonic 100-300 lens. Quality construction with a nice, tight fit. They function perfectly.
