Which Canon cameras use fluorite lenses?

Fluorite lenses are ED lenses. The so-called fluorite lenses are artificial fluorite, not natural fluorite.

The lens is on the lens and has nothing to do with the body. Canon's ED lenses are generally "L"-level lenses. L-level lenses are high-end lenses that are very expensive. They are all SLR lenses. There are no lenses with this lens on DC. Even the semi-professional grade G series.
