Fujifilm
WCL-X100 (black)
Wide conversion lens
This conversion lens will change the focal length of your Fuji X100 from a 35mm to a 28mm equivalent focal length, giving you a considerable wider field of view. Image quality is kept high even at f/2, thanks to a sophisticated optical design using four elements in three groups, and Fuji's optical coatings keep flare and ghosting to a minimum.
Note: to ensure proper operation, make sure your X100 has Firmware 1.30 or above installed, and turn on the Wide Conversion Lens mode.
