MAMIYA - Mamiya M645 Super Lens TechBulletin
by MAMIYAThis technical bulletin from MAMIYA addresses lens compatibility with the M645 Super viewfinder and the exposure compensation requirements. The document explains that the ultra-bright viewfinder of the M645 Super produces brighter focusing screens compared to traditional M645 cameras, which can result in overexposure when used with the M645 Super AE Prism Finder N. It features a comprehensive reference table listing seven different lenses (80mm/F4 Macro, 150mm/F3.5, 210mm/F4, 105-210mm/F4.5 Zoom, 145mm/F4.5 Soft, 75-150mm/F4.5 Zoom, 500mm/F5.6) and their compatibility with two compensative meter coupler types: Type A (P/N0.524804181) and Type B (P/N0.525204181). Technical diagrams illustrate the design specifications of both coupler types and their respective configurations. An important notice indicates that when using the 300mm/F5.6 lens with the AE Finder N, exposure compensation of 1 to 1.6/3 is required depending on shooting conditions. This bulletin serves as an essential reference for M645 Super owners seeking to optimize metering accuracy across various lens combinations.
