Most useful for Canon because they like to control the aperture electronically, but seems kinda fiddly and I don't have a lot of use for AF with macro anyway.

It's on my ToDo list to make something like this. I have an old 4/3rds body to extract the electrical contacts from and an Olympus 14-40mm kit lens (that isn't worth putting on the camera) to salvage the lens mount from. I just haven't figured out how to connect everything to the bellows setup.

There are quite a few dead camera bodies and lens available for the asking or for shipping costs, so experimenting shouldn't cost too much.

Much easier to get a coupling ring and reverse attach an old manual lens onto a longer lens.

Are you doing this on a Quanon? If so, how do you control aperture on the reversed lens?

If you're leaving the reversed lens wide open and controlling aperture on the "longer lens" mounted on the camera, you're taking a big hit on performance...
