Offering complete safety to the camera lens, the Fujifilm Rear Lens Cap is adept at resisting dust, dirt, water, scratches, and other hazardous factors. This front lens cap can be easily fixed onto the lens via its filter thread. Equipped with a highly progressive Super EBC (Electron Beam Coating), the Fujifilm 39 mm Lens Cap is equally competent at controlling ghosting, flares, and other types of distortion. It has maximum reflection of just 0.3% so that the picture quality is never compromised. It is also designed in a sleek, thin frame fashion, thus precluding vignetting while combining two filters. The Fujifilm Rear Lens Cap is especially designed to safeguard the Fujinon XF and XC lens mounts.
