For more than 6 years I have not been able to get new lens shades for the Zeiss 40mm FLE distagon lenses. Dr. Cam (Wulf Koehler) who has worked with the factory for decades has now made a high quality reproduction version of the shade. This attaches to the lens via a locking thumb screw like the 40mm Schneider shades and accepts standard 95mm screw in filters. It's really nicely made and works great! I have one in stock.
