Samyang/Rokinon 35mm f/1.4 focus wheel locked

I dropped mine onto a chair from two feet, and the aft focus group gained a millimeter of play and became decentered. A darn shame because when I sent it back to Bower, they replaced it (for $200) with an inferior copy (no play, though). My first copy was incredibly optically perfect, just the lens is not built strong enough.
