Kenko Auto Extension Tube Set for Micro Four Thirds Lenses

Kenko Auto Extension Tube Set for Micro Four Thirds Lenses
Key Features
  • Two Extension Tubes
  • Compatible with Micro Four Thirds Lenses
  • Use Individually or Combined
  • Macro Conversion
The Auto Extension Tube Set 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.

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 Auto Extension Tube Reviews

Solid. More than just closeup

By john

Purchased to explore macro photography. Happy with quality and results so far. Accidentally discovered that with 100 to 400 lens, they can be used for more than just closeup. I was able to take pictures of items about 15 feet away. The focal range is really small, but images are sharp.

Outstanding value for results

Kenko was recommended by my photography teacher. Because it transfers all lens settings to the camera, my pictures turn out great. Just inserted the extension tube in between lens and camera and was ready to shoot!

How cool is this?! Extension tubes for much less cost than a dedicated macro lens and that allow the camera body to talk to and maintain all the functionality of the lenses you mount. Maybe you don't get sll the functionality of a dedicated macro lens b ut you certainly get enough to allow you to explore this type of photography and decide if you want to take a deep dive into it Yes, I recommend these

Build quality is consistent with other reviews. They're not "premium" level, but solid and comfortable. As stated in the title, I am strictly amateur level, but learning. I used a 50mm Nikon prime lens, and struggled a bit with focus and light, but the payoff is coming. I was pleasantly surprised by the results. I would like to share a photo, but don't seem to be able to upload from my ipad where they're stored. I want to learn close up/macro photography and these seemed a neat way to begin. Overall, I'm quite happy with the purchase.

A winner!

Very well made extension tubes with contacts that allow auto exposure, etc. My Nikon 105mm macro lens doesn't wobble with 1, 2, or all 3 tubes used. Excellent product.

My old extension tubes were pretty banged up, so these were simply replacements. The old ones (18 years old) were rugged and reliable. These are built of the same quality and will serve my needs for years to come.

solid, high quality auto macro accessory

I bought these after having focus and exposure problems with a manual equivalent. Well worth the extra cost. Well made, durable construction.

question

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.

Can these tubes be used on a canon 100 mm EF macro lens and then with an EF to RF adaptor on a Canon R5?
Asked by: Clifford
Yes, you are able to mount the combination (Canon EF 100mm f/2.8 macro with the Kenko Auto Extension Tube Set DG on the EF-RF adapter) onto an EOS R5 and it should function as expected.

Will these tubes work with the D810 and the 60mm Macro?
Asked by: Debra S.
I don't have the D810, but it has a built-in AF motor to drive the old AF lenses, and the Nikon mount is the same. Should work just fine for you.
