The Contax GB-B1 Bellows Lens Hood is made for lenses in the Contax 645 range. The bellows design allows for adjustable shading dependant on which lens you are using. It is compatible with all lenses between 45mm & 120mm to prevent lens flare and maintain image quality. The bellows are in good nick, there’s some signs of use in the metal components that I believe to be consistent with an item of its age. The mechanism functions correctly and the dial rotates smoothly as does the locking dial. It comes boxed with original instructions and gel filter holder.
