The Argus C4 is one of the most high quality cameras ever made. The lens is coupled to the rangefinder for easy rangefinding. If that's a word. It has a "hot" shoe on top that is actually hot...not like the shoes on the C3 colormatics and matchmatics and C3 standards. There is a selector switch on the rear of the camera which allows you to choose from M or F. Some C4 models have a switch that allows you to choose from M or X. X being electronic sync. This camera has taken some of my finest photos (not that i take fine photos ;) )
