Nikon BC-5 flash unit. It is a compact, accessory flash unit designed for use with early Nikon rangefinder cameras such as the S2, S3, S4, and SP models. The unit uses disposable flashbulbs, which were common in the 1950s and 1960s. The reflector folds down to be very compact for storage and can be tilted for bounce lighting. This is an old, second-hand item. Please purchase only if you understand and accept the nature of vintage photographic equipment. Carefully review all photos, as they form an important part of the description. Ideal for Nikon collectors, vintage camera enthusiasts, or as a display piece alongside classic Nikon cameras.
