No such thing as a DX or FX only lenses, both are interchangeable. Just that when using a DX lens on full frame (FX) body it causes vingnetting in the corners of the image, other than that it's fully functional.
From what I've read, this comment deserves some scrutiny. If you take a Canon EFS model (DX) lens and try to install it on some full frame Canon cameras, you may very shortly be making new friends at a Canon camera repair shop. Canon publishes compatibility tables for just this reason. They warn about mirror damage, for instance.
Just a thought.
