PRO1D Pro Softon Clear (W) "Pro Softon" blurs bright stars, making constellations stand out from the many stars. It is a filter essential for astrophotography and is loved by many professional and amateur photographers. For "starscape photography," which captures the starry sky and scenery together, and in response to the demand "I don't want to apply a soft effect to landscapes such as mountains and buildings," it has about half the soft effect of the conventional Pro Softon (A). - Brand: Kenko - Model Name: PRO1D PROSOFTON Clear (W) - Size: 82mm - Type: Soft Focus Filter
