This camera is similar to the Sonne C. It has, however, a revised viewfinder/rangefinder arrangement (with one eyepiece instead of two and a larger viewfinder window) together with a different design of winding knob.
This model was flash
synchronized for X and M .
There are two variants of the C4, an early and late model. Early models generally have 'Sonne' and 'Germany Patent' engraved on the top plate. Coupled with the German name (Sonne), this often leads to some confusion. Possibly the manufacturer thought that German cameras (the Leica connection) would sell better. On later models 'Germany Patent' is replaced by 'Pat. Made in Italy' (see picture). Some late models also have the word Sonne (in script), together with a representation of the sun, on the front just below the small rangefinder window.
Despite its appearance, the knob on the front of the body is not a slow speed dial. It is a flash selection knob, marked 'E' for electronic flash and 'W' for FB.
The serial number is engraved inside the body.
