The PolaPlus was the "gold standard" instant back for Hasselblad professionals. Before digital screens, photographers used these to take "test shots" to check their lighting and exposure before committing expensive 120-roll film to the shoot. While many third-party companies (like NPC) made Polaroid backs for Hasselblad, the PolaPlus was the official high-end version produced by Hasselblad themselves. It features a larger, more comfortable film-pulling area and a smoother dark-slide mechanism. This unit is in museum-grade condition, appearing nearly unused in its original silver "blue stripe" box with the manual and official inspection certificate.
