Olympus Body Cap Lens 15mm F8.0
The Olympus Body Cap Lens 15mm F8 is a tiny, lightweight, inexpensive piece of kit that somehow squeezes a focusable three element lens into its 9mm-thick housing. Optically it doesn't win any plaudits, but in a way that's not really the point. Its real attraction lies in its portability and simplicity - you won't find a smaller lens.
