Upload & Sell: Off
I had read that they were thinking about offering something, but wasn't aware they had actually decided to do it. Additionally, I had heard the lens would have to be sent to Germany, so I decided to have it done here in the states... Given the lack of activity for this lens on the forums, I don't think very many have been sold. I doubt Zeiss is in any hurry to provide this service for such a small number of users wanting it done...
From what I can tell, S.K.Grimes has a very good reputation, and they did a great job on mine.
