The WCL-X100 Wide-Angle Conversion Lens for X100 Camera (Silver) from FUJIFILM converts the lens on your FUJIFILM X100 camera from a 35mm equivalent lens to a 28mm equivalent lens, giving you a true wide-angle lens. Even better news than that: Fuji engineers have treated the conversion lens and the original lens as a single unit, so that there is little, if any, loss in image quality.
