A couple months ago, Kenko announced a new set of macro extension tubes for both Micro Four Thirds and Sony NEX. These extension tubes make it possible to use any MFT- or E-mount lens for macro photography, by spacing it further from the sensor and subsequently retracting the closest focusing point. What makes these particular extension tubes special is that they feature electronic contacts which allow for communication between lens and camera, thus retaining full autofocus capability and aperture control. In this video review, we are presenting the Kenko DG Extension Tube Set for Micro Four Thirds. The NEX version has been briefly discussed in this article.
Kenko DG Extension Tube Set for Micro Four Thirds
The Kenko DG Extension Tube Set for Micro Four Thirds comes with two electronically coupled spacer rings that go between the camera and the lens. The tubes, which feature a full Micro Four Thirds mount on either side, are 10 and 16mm long and can be used alone or in combination. When used in combination, they space the lens a whole 26mm further from the sensor, which will turn pretty much any Micro Four Thirds lens into a serious macro solution. It is recommended, however, to always use lenses that have a focal length longer than the extension tube attached. Otherwise the lens may not be able to focus properly. Before we demonstrate the extension tubes in the video below, first the technical specifications from B&H’s product page:

Picture Gallery
Since we did not include a picture slideshow in the video, below you can find a gallery of pictures taken with both extension tubes used either alone or in combination on the Panasonic G1 and the Olympus E-P1. All pictures were taken with the Panasonic Lumix 20mm f/1.7 pancake lens.
Finally, I would like to thank HapaTeam GmbH in Germany for providing the review units.
