Kenko A-EXTUBEDG-M43 Overview

  • 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 26.
    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 Very well made. These work as expected for and auto extension tube set and are well suited to the MFT system. ?The quality is very good. ?The tubes engage very smoothly, like butter, ?with the M.Zuiko lenses I tried and the camera body, the EM1.2. ?The release buttons are easy to operate. ?Overall a great product. ?I was surprised to see they are made in Japan.

    Will these work with the Olympus 17mm 1.8?
    Asked by: Mauricio
    Although we have not tested the extension tubes with every MFT lens on the market, this combination should work well together.

    Would these work with the Leica TL or TL2?
    Asked by: Donna O.
    I dont believe so. I am not familiar with Leica. Leica lenses for the Panasonic micro 4/3rds cameras would work with these ext tubes. TL and TL2 are APS-C so I dont believe so.

    Just purchased these and am having an issue getting any image. Using the panasonic 12-35mm, i have used one and both extension tubes and still only get a blurry image of light. I've gotten very close (cm close) to an object with a tripod and have slowly backed away to test the range and still get nothing. i have used mostly manual focus but have also tried auto, and both do not change the blur that I am getting. has anyone else had this issue?
    Asked by: John L.
    Just tagging this, my opinions in general, given 30+ years with extension tubes, helicoids, and macro work. Tubes on Wide angle lenses can work, depending on focal length, but “one size does not fit all.” Super-wides not so much, imo! My experiences with tubes & zooms are okay, but not always real good. Lens designs dictate the outcomes. Some zooms are great throughout their range and others are less great at varying points of extension. In many respects, dedicated macro lenses are optics plus a focusing (helicoid) tube. Getting the flat visual field for edge to edge sharpness is very important for macro work - thus dedicated macro lenses exist. Adding a tube to your main lens changes the focusing distance but the curvature of your optics also remains. You may find sharp lens center, but softer edge, depending on the degree of magnification (tube length etc). If you are merely trying to shorten a distance for close-up, portraits, etc, then tubes can help. If you want a critically accurate, edge-to-edge consistent combo, then a macro lens is usually best. These are tools for defined tasks and you may want some of each eventually.

    Hi, I own a GH4 with a panasonic 20mm 1.7, and a 45mm 1.7. Will it work with the kenko extension tube?

    You shouldn't have any problems with this combination.

    I used it on my canon but didn't find it much useful. Hence bought Macro lenses.
