Product description 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).
