Olympus 9mm F8 Fish-Eye Body Cap Lens
The Olympus 9mm F8 Fish-Eye Body Cap Lens is, as it name suggests, a simple super-wide-angle fisheye lens contained within a body cap. Strictly speaking an 'accessory' rather than a 'lens' (at least from Olympus' point of view), it offers a 140 degree angle of view and a fixed F8 aperture. Despite being a mere 13mm / 0.5" thick, Olympus has still managed to squeeze in a five element optical system with two aspherical elements, along with a simple lever-operated manual focus system.
