Fujifilm MCEX-11

Two types (11mm, 16mm) available - You can choose from the two types of tubes depending on the level of magnification you require.
Electronic connections automatically pass information between Fujinon X Mount lenses and FUJIFILM X Series camera bodies so you can still use autofocus and control the aperture while using the tubes.
The mount rings of both tubes are made of high-grade solid metal and are precisely manufactured to suit the XF lenses and the X Series interchangeable cameras perfectly.
