Let's hope an AF-adapter Canon EF - Fuji GF is released soon.
I emailed Cambo and asked if their upcoming Actus version for the GFX would allow the use of their Canon lens board with electronic aperture control. They sent me a very detailled answer. I really like Cambos open way to respond to customer questions and discuss possible future products. Here is what they said about the Actus and Canon lenses:
"The Fujifilm G mount has a focal flange distance (FFD) of 26.7mm, the Canon lens has a FFD of 44.0mm, than you will have a distance 17.3mm left, this is not enough space to construct a front and rear frame including a bellows to achieve tilt, swing and shift movements. So unfortunately within the Actus system it in physically impossible to use Canon lenses on the Fujifilm GFX camera.
Therefore we are thinking about designing an fixed adapter between the GFX camera and Canon lenses, this way the Canon TS-E lenses can be used on the GFX and you have still some tilt/swing and shift options for the TS-E lens itself. "
So when Metabones does not plan to do something for Canon lenses with aperture control - it looks like Cambo might do that. For my TS-Es I even prefer a fixed adapter to the Actus solution. If you want that too: send Cambo an E-Mail and request for such a product.
