Hasselblad B50 Bay 50 Proshade Compendium Bellows -Read-
This is a really cool matte box style shade for Hasselblad cameras. It comes with a Bay 50 mount, which fits most of the C and C T* lenses.
This one is in excellent condition and works perfectly. The bellows are sharply pleated and light tight. All of the movements are smooth and lock securely.
