It looks like Canon is discontinuing EF lenses at quite a fast pace. This time I have been told that both the Canon EF 70-200mm f/4L IS USM II and Canon EF 85mm f/1.2L USM II have been discontinued.
Keep in mind, even if a lens is discontinued from production, you're still going to be able to find inventory in certain stores for a while.
I have added a page with a list of recently discontinued Canon EF lenses to the left menu. I'll keep track of every lens that Canon discontinues over the next little while.
