Are there adapters to go from EF to old mounts?

I find I'm shooting and developing more and more film. I have a ton of different film bodies and associated lenses, but I'd like to try out some of my EF/L lenses on some old film bodies. Yes, I have a few EOS film bodies, but I'm thinking about trying them on some Canon FD, Minolta MD, or Fujica bodies. Because of the flange to focal plane distance of those cameras, they should work without the need for glass in an adapter. Also would love to try them on an old Kodak Retina (DKL mount) or maybe even a Voigtlander.

I know it's a step backwards and quirky, but I think it might be fun.

So does anyone know of an adapter that would let me step back in time?

How would you control the aperture?

I've heard of the other way around but as the post above states, how are you going to control the aperture. It's not manually settable.

Not worried about aperture control. this is more for fov range. I have a full range of EF/EF-s lenses from 8mm to 300mm, whereas with my old glass, my range is from about 28mm to 135mm. Plus, it's really just for fun.

Hopefully this isn't too redundant: when canon introduced the EF lens mount in 1987, one of the labels applied to the line of cameras that used the mount was "Electro-Optical System," or EOS. Along with autofocus, the EF lenses abandoned the FD lenses' mostly mechanical aperture control for an electronic control system operated by each camera body.

"Fun" could mean duplicating third-party lens manufacturers' feat of reverse-engineering the Canon EF lens exposure system, or carrying a large box of graduated neutral density filters to get correct exposure with EF lenses on other camera systems.

OMG

I started some years ago with Canon EOS DSLR cause that camera allows many lenses to be adapted - it has a low register distance for a DSLR and a wide mount diameter.
This are exact the reasons why it is extreme hard to adapt Canon EF lenses to an old 24x36mm SLR camera!
So you have probably luck with Alpa (not Sony) or Olympus Pen F (this is only halfframe) SLR cameras - and a homemeade adapter - if you want to reach ~infinity.
The cameras you mentioned seem to need a major mount conversion to reach infinity with most EF mount lenses. Some EF lenses may have enough focus throw behind infinity, so they probably could be used with infinity, but I think this are only the very long ones.

You have not only to consider the register distance, but also the 6mm protrution for the rest of the EF mount, and even ~7.5mm for the EF contacts.

I would say it is a very high effort to adapt EF lenses to SLR photo film cameras others than EF mount ones (if you want infinity). I have made a Contax/Yashica lens to M42 camera adapter, but not with infinity in mind - was for macro.
