Hasselblad Eye-Level Prismfinder HC-1 consists of a lens and prism technology of extreme high optical quality. It provides a vertical image about 2½ times the size of the image appearing on the ground glass screen. Prismatic chassis promises viewfinder stability. A correction lens to compensate for mild eye imperfection is easily inserted into a groove in the rubber eye-piece shield. This finder has a release button for change of magazines.
