Pre-war Leica IIIA from 1936 with expanded slow speeds, refined screw-mount rangefinder with collector significance.
The Leica IIIA (Model G) is a vintage Leica screw-mount rangefinder from 1936 that added slow shutter speeds down to 1 second to the Leica III specification. The IIIA was an important refinement of the pre-war Leica rangefinder design, expanding the shutter speed range for low-light and creative photography.
The addition of slow speeds expanded the camera's versatility significantly, enabling long exposures and low-light work that the Leica III's faster-only shutter could not achieve. The camera uses the L39 screw mount for Leica and compatible lenses.
Build quality is pre-war Leica precision with machined brass and chrome finish. The 1936 manufacture reflects the peak of Leica's pre-war production, and the camera represents a refinement of the design that established 35mm photography as a serious medium.
The Leica IIIA holds strong collector value as a pre-war Leica rangefinder with expanded slow shutter speeds. The historical significance of 1930s Leica production and the L39 mount compatibility give it both collector and practical photographic appeal.
