Olympus Fisheye Body Cap 9mm f/8 Lens
This 9mm f/8 (35mm equivalent focal length: 18mm) fisheye lens can also be used as a body cap. It consists of 5 elements in 4 groups including 2 aspherical elements, maximising the use of optics in the lens and providing enhanced performance. The MF lever that also works as a lens barrier lets you switch between deep focusing and close-up shooting with a single action. Image stabilisation is also effective when you set the focal length manually.
