This 52mm soft filter provides a soft, dreamy effect. According to the manufacturer's description: This soft effect filter produces a beautiful soft glow. It can be used with a wide range of lenses, from ultra-wide angle to super-telephoto, and without any aperture restrictions. It is also used in astrophotography, such as for photographing stars and landscapes with stars. This is the "Pro Softon" with a weaker effect, suitable for wide-angle to telephoto lenses. It's ideal for those seeking a subtle effect or for use with telephoto lenses, which tend to produce a stronger soft effect. The item has been opened, but it is unused and has been stored carefully. The filter is in perfect condition, with no scratches or marks. - Brand: Kenko - Model Name: PRO1D Pro Softon [A](W) - Filter Diameter: 52mm - Type: Soft Filter
