Leitz 39mm Yellow Filter for 50mm f2 Summitar - Black - Condition:Boxed

Leitz 39mm Yellow Filter - Black- for Leitz 50mm f2 Summitar Lens - Condition: Excellent 
 
Very hard to find.
At the pinnacle of lens filter quality. An original Leitz Filter. As good as it gets in terms of quality. Some brassing and signs of use on the rim, a couple of tiny marks on the lens galss perimeter that will not affect the image in any way, over all lovely. 
 
The Yellow Filter is a particularly useful filter for darkening skies and creating contrast.
