BRONICA - Bronica 150S
by BRONICAComprehensive technical service manual for complete disassembly, maintenance, and reassembly of the ZENZA BRONICA ZENZANON 150/3.5 S lens. This workshop repair guide delivers detailed step-by-step procedures for accessing internal lens components to facilitate shutter replacement, optical cleaning, and correction of lens defects. The manual specifies all required specialized tools—rubber cone, spanner wrench, and JIS screwdrivers—with each disassembly phase illustrated through high-resolution photographs documenting the full sequence from nameplate ring removal through shutter unit extraction. A substantial technical section examines both Seiko #0 shutter generations (original and updated versions), detailing their specifications, diaphragm control circuit schematics, and six-pin electrical contact pinout correspondence. Wire color coding tables guide shutter reconnection during reassembly, while critical reassembly notes ensure proper mechanical and electrical function. Additional coverage addresses lens contact specifications and aperture control circuitry across different shutter generations, along with maintenance recommendations for sustained optical performance. An essential parts list completes the documentation. This practical reference serves camera repair professionals and dedicated lens maintenance users.
