The Kenko Extension Tube Set for Micro 4/3rds is made up of two extension tubes, one 10mm and one 16mm. They can be used together or individually to increase the magnification factor of Micro 4/3rds mount lenses. They feature electrical contacts to transmit autofocus and aperture control, and offer a 0.5x increase in magnification when used together.
Do keep in mind that when extension tubes are used, you will loose up to 3-stops of light. This can affect autofocus performance, so we’d suggest sticking to manual focus. In addition to this, you will not have infinity focus while using extension tubes.
