Mine is nothing like this I had two or three spots after 700 shots and several lens changes as I was trying out all my lens and they easily blew off with a rocket blower. Yours does seem to be dust/debri vs oil but that is a ton of junk. What aperture are you at not that it matters that much mess is not acceptable. Good luck keep us informed on your outcome. But I do agree this is not usable.
