I used this about 10 years ago with an EOS KISS X7. I probably took it out a few times. There are no noticeable scratches on the lens. I don't have any cleaning tools, so I've lightly wiped it with a microfiber cloth. I haven't completely removed any haze with alcohol. It's in the condition shown in the photos. Excerpt from the manufacturer's website: [Product Features] ■ A filter that provides a very smooth soft effect with beautiful light diffusion. ■ Special coating and very fine special effect processing on the filter surface. ■ Can be used with a wide range of lenses, from wide-angle to telephoto, without any restrictions on the aperture value. ■ Suitable for various scenes such as landscapes, flowers, portraits, and nightscapes. ■ Pro Softon is also a standard filter for astrophotography. ■ Effectively diffuses light, leaving the core of the focus while beautifully blurring the light into a round shape. ■ Bright lights will blur and appear larger, making constellations clear. ■ Multi-coating reduces reflections on the glass surface. * The soft effect of soft filters becomes stronger as the focal length of the shooting lens increases.
