Rare and highly collectible Kopil KSS Folding Bellowscope designed specifically for Exakta mount cameras. This is a precision-engineered vintage macro bellows focusing unit made by Kopil (KSS), a Japanese optical accessory manufacturer. The bellowscope allows for extreme close-up and macro photography by extending the lens-to-film plane distance on Exakta bayonet mount cameras such as the Exakta Varex, VX, and related models. This folding bellowscope features a robust all-metal construction with a black crinkle-finish body, dual knurled adjustment knobs for horizontal and vertical shift movements, a calibrated rack-and-pinion focusing rail with millimeter scale markings visible (0.7 through 20mm range indicated), and a precision Exakta bayonet mount interface plate. The unit folds compactly for storage and transport. Condition: Used but appears to be in very good to excellent condition. The metal body shows minimal wear. The rack-and-pinion mechanism appears smooth and functional. Comes in its original blue KSS presentation box with original yellow chamois cloth padding and original plastic wrapping still present — suggesting this item has seen very limited use. Box shows age-related wear with some soiling and corner wear but remains intact. What's Included: - Kopil KSS Folding Bellowscope unit - Original blue presentation box - Original yellow chamois cloth A truly hard-to-find accessory for Exakta collectors and macro photography enthusiasts.
