Official firmware for the legacy Olympus Camedia C-50 Zoom is no longer actively supported or directly available from OM SYSTEM, as the company has discontinued support for these older models. Users seeking to update or troubleshoot this device should be aware that modern xD-Picture cards may face compatibility issues, and hardware issues are more likely to be caused by battery or contact degradation than a need for a firmware update.
