Didn't get paid to say this. Makes no sense to buy OEM when they are probably being made in the same factory. You get more bang for your buck with these. Got them on my D810 right now.
Canon EF 85mm f/1.2 II L AF USM Lens

Big and powerful
I would like to say a few things. The autofocus is slow. It's not very slow, but it does get annoying (only at widest aperture). To combat this what I do is use Magic Lantern software and turn focus peaking on. This method is much faster than letting your autofocus sit there forever trying to figure it out. MTF Charts show this lens performs a lot better at f8 but who cares about that when the results are still pleasing and let alone UNIQUE on f1.2
Haven't had the lens that long to rate its durability but it is their top end 85 so one can only expect durability.
