Sunpak Canon module on a Nikon
 

Would I cause any damage to a Nikon body if I were to use the DED
module for Canon on it? I'd rather not spend more money if it works on
both without a problem.

I'm using a Sunpak 344D on a Canon AE-1, and basically want to know if
I can use it on a Nikon FM safely.

Thanks.
