THE ITEM The Sonnar 2.8/18 cm, nicknamed “Olympia-Sonnar” by collectors, is the bright telephoto designed by Zeiss for the 1936 Games. This specimen belongs to the Flektoskop generation, which converts a Contax rangefinder into a viewfinder reflex camera with ground-glass focusing. This is the late variant painted black with anti-reflective coating T (red marking). The optical number corresponds to 1941 production. These black T-treated versions were produced in very small series, unlike the far more widespread chrome versions.
