This Mamiya Eye-Level Prism Finder is a prism viewfinder designed for the Mamiya C330 and C220 twin-lens reflex cameras. It allows you to compose images at eye level rather than looking down through the traditional waist-level finder. This is particularly useful for portrait photography and for photographers who prefer a viewing experience similar to that of a conventional SLR camera.
The prism finder is an alternative to the standard folding waist-level finder and provides an upright, correctly oriented view of the subject. It is a useful accessory for photographers who want a different handling experience with their Mamiya TLR camera.
