This is the strong contrast black and white filter. If you want dramatic skies and your friends looking like vampires then this is the one that you want. It is Rollei Bay I (28.5mm) and fits all of the Tessars and Xenars with bayonets as well as most Yashica TLR's.
This one is in excellent condition with clean scratch free glass. The mount shows very light wear.
