Hasselblad Meter Prism Finder
The Hasselblad meter prism finder offers through-the-lens exposure measurement technology. The meter prism has a 45° viewing angle parallel to the optical axis of the lens. The Cds photocell computes the entire focusing screen with the exception of a few millimeters at the top edge. The precise light value is displayed on a scale visible in the viewfinder. The unreversed viewfinder image is enlarged by 3x magnification. The meter prism finder is battery powered. With normal use the PX625 battery has a life span of approximately one year.
