Our lens hood for the Fujinon XF 18mm f2 is a bayonet mounted lens hood. The photographer can still use their 52mm filter under this hood. The hood is extremely compact, measuring only 14mm in length. The hood comes back towards the focus ring, which creates the illusion that it is a continuation of the lens rather than an obvious add on like other hoods available for this lens. Each hood comes with 1 silicon lens cap.
