Fuji X aperture ring

[stanma]

Hi. I see the Fuji X lenses have a physical aperture ring. Is this mechanical or is it electronic? Can I use a Fuji X lens on another camera with a non-electronic adapter and still have control of the aperture though the ring?

None of the settings on X series cameras are mechanical

Ok, thanks.

Not even manual focus on the FX 14 mm f/2.8 R, with the clutch? You engage manual focus by sliding the focus ring rearward, which reveals a distance scale that you can read against classic DOF markings for different apertures. I have this lens, and just tried turning the focus ring with the lens not mounted on the camera. Looking into the rear of the lens, I see something shifting in re the aperture stop as seen through the glass. Not sure but I think this lens design might be a dozen years old. Sliding the focus ring forward disables it and makes the lens autofocus.

I'm not disagreeing, I'm just curious. I have wondered what's going on in there.

You may be right - its not a lens I've used - I was hoping someone would chime in and correct me if I was making too broad a statement

One way you can tell is if the ring continually rotates or has hard stops. If the ring rotates all the way around and keeps going, it is by-wire or electronic. If it has hard stops, it is mechanical. The XF-14mm f2.8 lens is a mecha lens.
