Does anyone know whether Leica CL 1973 film camera can be using on 35 (KOB) and 50 mm (Rigid) Summicron. i’d now prefer to take a small camera than M. Mine appears in the viewfinder using 40 and 50 mm frame line. i can take it along with a wider 35 mm Cron but don’t know whether the rangerfinder in CL will be acculate on 35 and 50 Cron or not. Any help would be appreciated. Thanks.
