Olympus
15mm f/8 Body Cap lens (black)
Ultra wide lens and body cap in one
This unique wide-angle lens also doubles as a protective body cap for your camera sensor. While protecting the sensor and internals it gives an ultra-wide angle, pan-focus snapshot lens. Useful when there is no time, or need to mount another lens to your camera. In 35mm terms it gives a field of view of about 30mm at f/8. Comes with a manual focus lever for closer focusing.
