The Olympus Body Cap BC-1 is a protective accessory specifically designed for E-System digital SLR cameras. This black plastic cap measures approximately 4.6 cm in diameter and weighs only 5 grams, providing lightweight protection without adding extra bulk. It securely covers the lens mount of the camera body when no lens is attached, preventing dust, moisture, and dirt from entering the sensitive internal components. The BC-1 is compatible with Olympus E1 and Evolt E300 digital SLR models, as well as with EC14 teleconverter and EX25 macro extension tube accessories. Made from durable materials, this body cap preserves the internal environment of the camera during storage or lens changes. Its simple snap-on system ensures quick mounting and dismounting, while its compact design makes it easy to carry as a spare. The matte black surface matches the aesthetics of Olympus camera bodies, and its minimal weight ensures it does not affect the camera's balance or handling. This essential accessory helps maintain optimal camera performance by protecting the lens mount contacts and mirror mechanism from environmental influences during transport or when switching between specialized photography setups.
