The effective image stabilization of the lens allows for up to five stops of compensation to counteract camera movements and avoid blurry shots. The lens is sealed at more than 20 points, making it both splash and dust resistant. To achieve the highest possible sharpness and maximum contrast from wide-angle to telephoto, the FUJINON XF18-135mm uses high-quality glass, including four aspherical lenses and two ED lenses. The special HT-EBC coating also minimizes surface reflections. The FUJINON XF18-135mm features internal focusing, utilizing a lightweight focus lens and a linear motor.
