I just learned that they make an adapter that goes from A-Mount to my M-4/3 cameras, the unique (to me, anyway) feature is an aperture ring with a mechanical connection to the lens. I see they have one for Nikon Z as well, probably others.

Anyone use one of these? How does it do? I ordered a Fotodiox through Amazon. I figure if it sucks I'm out $20, cheap enough for an experiment.

I'm such a Luddite...

I have an A-mount to Pentax Q adapter with an aperture ring and a Pentax DA to E-mount adapter with an aperture ring. Both of those work fine. There are no click stops on either. Most of these are made a bit short to ensure infinity focus but that can cause issues with non-unit focus lenses.

I have one branded Kecay, paid 20, that does the same from Amount to E mount. It has a pin, moved by a ring, that moves the diaphragm lever on the back of the lens.

Does the job for the cash, major drawback is that there is no precise control of aperture. I usually set it standing from full aperture and closing it while reading the exposure time variation

I used to have similar one going from Nikkor G lenses to e-mount. While it did work the problem was you couldn't tell the the aperture setting.

Thanks. I figured it may take some homework to determine the settings, but once you sort it out it'd be pretty straight-forward.

Here's a quick shot using a Maxxum 50/1.7 on an M-4/3 body. The aperture control is easy to sort, put the camera in P and starting at one end or the other, move the ring and watch the shutter speed. Easy enough to figure out.
