Electronic contacts allow you to shoot with AF and AE using the tube.
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.
Designed exclusively for the XF lenses and X Series cameras
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.
