Plasmat Satz Ser4 9×12
It introduces two lenses (Plasmat) of the larg eformat camera. One is DOPEL. Another one is SAZT. Even if the name is different, it is the same lens. DOPEL Plasmat Lens is barrel lens. Sazt Plasmat Lens is addition lens shutter These two lenses are described clearly in a double Plasmat and catalog generically. The interesting one can detach the front side and the rear side of the lens, and can combine lenses of various lengths. My lens includes the lens of 27cm, 22cm, and 15cm.
The combination It becomes 27cm+22cm= 15cm F4 lens. It becomes 27cm+15cm= 12.5cmF5. It becomes 22cm+15cm= 11cm F4.5.
