Cambo made an auto-aperture adapter not long after the gfx came out. It does not transmit exif data to the camera, but does have electronic contacts on the lens side to power the closing down of the aperture. It has a small LED screen on it so you know what F-stop you are at. It was designed around using the Shift lenses as it has a larger lens throat than what is typical on the other „smart“ adapters. I tried one of those (I don‘t recall which now), but it caused a lot of flaring on the sensor. The Cambo one does not, it works well. I‘ve had one for years and it has worked well for me. I believe it may have been discontinued, so you might have to look for a used one… https://www.cambo.com/en/view-cam/lenses/ca-gfx/
Has anyone found an adapter that DOES work with either the 24II or the 17?
