It came back with a note from the technician indicating that it had been tested on the company's test bench and pronounced 'within spec'. He sent it in because he didn't think the lens was in good order. Then again, I'm reminded of a story Roger Cicala from LensRentals told of the time he got a camera and lens back from one of the big companies (he wouldn't name it). I'm sure Rodenstock would have a much more professional setup.
