Linhof Technorama 617 S III mounting plate for the Schneider Super-Angulon 90mm f/5.6 XL, including the mounting foot of the protective impact ring. To mount a non-Technorama lens, additional components such as the focusing helical are required; compatibility and required parts should be confirmed directly with Linhof. In good condition. From a pet-free, smoke-free household.
