This Lens Cap Leash is designed for Fujifilm lens cap, preventing you from ever losing your lens cap again. Crafted with a leather‑like pad and strong 3M adhesive backing, plus a durable polyester cord, it securely attaches your lens cap to the camera's strap eyelet. Simply clean the lens cap, peel off the sticker, press firmly onto the cap, then tie the cord to your camera strap mount. For best results, allow 24 hours of rest before pulling or stressing the leash. Please check the diameter (Ø43mm, 49mm, 52mm, or 58mm) printed on the back of your lens cap – each size fits a specific list of Fujifilm lenses, including XF35mm F2, XF23mm F1.4, XF18‑55mm, and many more. Please note: This product includes the anti‑loss strap only. The lens cap is not included. It is intended to be attached to your existing lens cap. A simple, effective solution to keep your own lens cap safe and always within reach.
