De exacte functie is niet gecontroleerd. Manufactured by the specialised optical institution Astro-Gesellschaft Bielicke & Co. in Berlin, the Pan-Tachar 50mm f/1.8 is an extraordinarily scarce milestone in high-speed optical engineering. Developed under the groundbreaking 4-element, 4-group patents protected by the Deutsches Reichspatent (DRP) and US Patent 1540752, this lens was initially designed to cover 35mm moving-picture film with exceptional centre sharpness and a highly distinctive, artistic swirling bokeh profile. Finding a pre-war cinematic prime factory-configured or systematically adapted into a rangefinder-coupled Leica M39 mount transforms this asset into a premier artefact for legacy glass collectors and modern analogue purists.Technical Condition and Specifications (The Technicals)Brand and Model: Astro-Berlin Pan-Tachar 1:1.8 50mmManufacturing Year/Era: c. 1930s (Early pre-war production sequence)Serial Number: Visually registered as № 23505
