The Hasselblad Prism Sports Finder is a compact open-style sportsfinder with a few clever additions: there’s a telescoping rear sight for parallax correction, polarized surfaces on front and rear sights to confirm alignment, and a reflex system which lets you focus visually on the camera’s groundglass. The front sight includes framelines for 80mm, 150mm, and 250mm lenses on 6x6 (and there's an additional front sight for use with 6x4.5 backs). In excellent condition, with minor paint and finish wear.
