MAMIYA - Mamiya M645 M645 1000S Service Manual
by MAMIYAComprehensive service manual for the Mamiya M645 and M645 1000S medium-format SLR camera systems. This workshop reference delivers complete technical specifications for the professional 6×4.5 cm camera body, detailing the electronic focal-plane shutter mechanism, compatible 120 and 220 roll-film formats, and the standard Mamiya-Sekor C multi-coated lenses with automatic diaphragm control paired via the M645 bayonet mount.

The manual addresses battery requirements, focusing techniques, and the interchangeable focus screen with split-image rangefinder aids for precise composition. Additional sections cover the instant-return mirror with lock-up capability, multiple-exposure functionality, and variable shutter release delay adjustments. A dedicated troubleshooting guide provides systematic diagnostic procedures to identify and resolve operational issues commonly encountered during field use and maintenance of these professional instruments.
