I use FD lenses on my T3i and 80D with adapters, but does anyone know if it can be done the other way round?

I have two good condition T90 bodies and would like to use some of my EF lenses on them.

Does such an adapter exist and if so, what is it?

Thanks in anticipation.

Not unless you can change the laws of physics. T90 - and all FD cameras - have a smaller lens flange than ef lenses. If you could make an adapter you could perhaps make it physically fit but it would throw the optics off so that you couldn’t focus.

Not likely. Here's a website with a discussion on the subject: https://photo.stackexchange.com/questions/60742/are-there-any-adapters-for-using-ef-lenses-on-fd-mount

Many thanks for the responses, confirming my expectations. I have bought a used FD 100-300 lens, which should meet my needs.

No you cannot.
Your EF lenses are all electronic including aperture control.
Thus will not function on a FD mount (Same exact mount as the FL and R "Mounts")
For this reason and the flange differences no adapter has ever been commercially made that I am aware of.
Be advised, if you get a Canon RF mount camera ALL your EF lenses will work perfectly as designed and all features with the Canon EF to RF adapter. Additionally the R cameras work with the R, FL and FD lenses. They must be manually focused and manual aperture control but they were designed that way as many cameras they mounted on were fully manual. Newer FD cameras did utilize an auto aperture adjustment feature such as on the EF and F-1 cameras among others.

The easy answer is no, it's not possible. The T90 is a mechanical control system and the EOS lenses are electronic in nature. There is no adapter to correct this.
