ZEISS IKON - Zeiss Jena Sonnar 180 2.8 Service

This comprehensive service manual covers the complete disassembly, cleaning, and reassembly of the Zeiss Jena Sonnar 180 2.8 lens for Pentacon Six camera bodies, specifically addressing the Zebra version. Designed as a workshop reference for technicians and serious vintage camera restorers, this repair guide documents every step of optical and mechanical component servicing with hands-on precision. You'll find systematic procedures for removing the front ring, front optical element, support ring, the middle optical group with its three cemented lens elements, and the rear element assembly. The manual includes specific tool requirements—spanner wrenches, rubber wrenches, and practical workarounds using improvised implements like empty tape spools—ensuring you can work efficiently without specialized equipment. The maintenance and cleaning section prescribes proven techniques: isopropanol sterilization of optical surfaces, alcohol or vinegar-based glass cleaners for coatings, and targeted approaches for unsticking seized components. Reassembly guidance emphasizes cotton glove protection, careful hand-blower dusting between each stage, and proper element securing without over-torquing. Detailed photographs of disassembled parts and the complete toolkit make this troubleshooting guide an indispensable reference. The content reflects genuine workshop experience rather than theory, giving you the confidence to undertake restoration of this prestigious professional-grade optic.
