Kenko AF Extension Tube Set for Micro 4/3rds and Sony E mounts consists of a 10mm and 16mm extension tubes that can be used individually or together4.
The Kenko extension tubes have all the contacts and circuitry to maintain
communication between the camera body and the lens. AF (within the limited macro range) and auto exposure are maintained with these extension tubes1.
Extension tubes are designed to enable a lens to focus closer than its normal set
minimum focusing distance. Getting closer has the effect of magnifying your subject (making it appear larger in the viewfinder and in your pictures). They are exceptionally useful for macro photography, enabling you to convert almost any lens into a macro lens at a fraction of the cost while maintaining its original optical quality.
The DG extension tubes have no optics. They are mounted in between the camera body and lens to create more distance between the lens and film plane. By moving the lens father away from the sensor in the camera, the lens is forced to focus much closer than normal. The greater the length of the extension tube, the closer the lens can focus.
1. Depending on available light and due to a very shallow depth of field manual
focusing may be required if the lens AF will not lock focus.
2. Focal length of the lens should be longer than the focal length of the tube for
3. Also, Kenko recommends using a tripod for sharper results during macro
4. Stacking is not possible with the Panasonic 45MM Macro and PZ 45-175MM
lenses. However all Panasonic and Olympus lenses work with either the 10mm
or 16mm separately. If an error message is displayed when trying to use the
tubes together on one of these lenses or any other please use one or the other
extension tube separately.
