Description: Born from a joint venture between Leitz and Minolta, the Leica R4 is the first compact single-lens reflex camera of the German manufacturer after the huge and heavy Leicaflex, Leicaflex SL, Leicaflex SL2 and Leica R3. Its production started in 1980. Its performances aren't exceptionnal when compared to the competitors of its time (like the Olympus OM1) but it allows to use the legendary Leica R lenses (in their 3 cams version).
