The Olympus Body Cap 15mm f/8.0 is an ultra-thin wide-angle fixed-aperture prime lens for Micro Four Thirds cameras.
Being only 9 mm thick, the lens is always ready for wide-angle photography. It has only two focus positions - close-up (0.3 m - see Photo 3) and infinity (see Photo 4). The minimum focal length of 0.3 m makes it possible to take interesting close-up pictures. Its ultra-compact size and a dedicated shutter, covering the front lens (see Photo 2), make it possible to use the lens as a body cap. Despite its having optical elements, officially it is not a lens, but a camera accessory.
