This is the FUJIFILM WCL-X100II. It's a dedicated wide conversion lens that expands the focal length by approximately 0.8x, resulting in a 28mm (35mm equivalent) field of view. It's effective for capturing the powerful perspective that characterizes wide-angle lenses, as well as for shooting in tight spaces or vast landscapes, allowing you to capture a wider range of subjects. I purchased it new in August of this year and have stored it in a dry cabinet with minimal use. It's in very clean condition. I'm also including the optional lens cap and protective filter. - Brand: FUJIFILM - Model Name: WCL-X100II - Lens Diameter: 49mm - Features: SUPER EBC FUJINON - Accessories: Lens cap, protector Thank you for looking.
