Argus C4 Geiss

The Argus C4 was an attempt by Argus to improve on the C3 model by combining the rangefinder and viewfinder into a single eyepiece; and restyling the body into a smaller and more modern-looking design. However in one respect the C4 was a step backwards, in that it offered no option for interchangeable lenses, which the C3 had offered (albeit inconveniently).
