Schneider-Kreuznach Linhof Super-Angulon 90mm f8 brand_Kessler Tap the rear button toThis is a "Linhof Select" 90mm f8 Super Angulon in a good 00 Synchro Compur shutter. Lens has minor internal dust, minor rim coating loss. Regarding the rim coating loss: this is a common issue with older Schneider lenses, where the dark paint on the rim of the glass element separates; it's not in the optical path and it never will be, it just looks spooky. Includes retaining ring.
