By contrast, I've only once needed to return a LF lens - and it was obvious that hey just simply shipped the wrong lens. It wasn't even close - except the focal length was the same as I had originally ordered. Unfortunately, they did not have the lens I ordered in stock. So, got a refund and bought one from Jim at MPEX.
