I have a Soligor 35-70mm lens marked C/FD and I'm trying to mount it on my Canon AT-1. It doesn't seem to click on the usual way. Do I need an additional mount or adapter, or is there a different way to attach some Canon FD lenses?

There are two versions of the Canon FD lens mount. Both versions will work on your camera, but they attach and lock differently. With the original FD mount (which this lens may be), there is a ring at the back of the lens, behind the aperture ring, that needs to be turned in order to lock the lens onto the camera body. With the "New FD" or "FDn" mount (well, in 1979 it was new) you turn the whole lens (like you do with most lens mounts), which means that you need fewer hands to juggle lenses as you change them, and it's a lot easier to work with gloves.

Yes—if the lens is truly Canon FD/C-FD mount, it should fit your Canon AT-1 without any extra adapter. The likely issue is that Canon used two FD mount styles that lock differently.
With the original FD mount, you do not rotate the whole lens to attach it. Instead, you seat the lens on the camera and then turn the locking ring at the rear of the lens (behind the aperture ring) to lock it in place.
With the later New FD (FDn) version, you mount it more like a modern bayonet lens by turning the whole lens.
So you probably don’t need a separate mount—just the correct mounting method for that version of the FD lens. If it still won’t fit, double-check that the lens is actually Canon FD and not a similar-looking mount.
