After weeks - months - a long time looking I finally found on ebay the dedicated lens shade for my barndoor Voigtlander Vitessa L. While it was still more than I wanted to pay it does come with a leather case to hold it and three filters, which as Vitessa fans know are made of Unobtanium. And I have three of these little gems! Bwahahahaha.... [laughs hysterically and mumbles something about My Precious....]
