Shocking! DON'T USE! This company shipped a lens that never worked. It couldn't focus and despite several attempts to micro adjust the focus, it still didn't work. Just to be sure, I took the lens to an authorised dealer who confirmed that the lens was faulty. I off-hired the lens early, shipped back at my own expense and requested either a refund or exchange. LensPimp said they'd shipped the item out in full working order and it had been returned with focusing issues. They never addressed the fact that it had evidently been damaged on route to me, and not responded to any of my requests for a refund or replacement. SHOCKING BEHAVIOUR!
