Kenko Center Image 52mm filter. This product is discontinued. Please refer to the manufacturer's website below for details on its effects: https://www.kenko-tokina.co.jp/imaging/filter/soft/4961607352335.html This is an interchangeable filter that allows you to sharpen the center image and make the surroundings appear white ("Sand Screen") or create a soft focus effect ("Soft Screen"). It's a rare type of filter these days, with interchangeable glass elements that are set between two frames and secured with screw threads. The Sand Screen is missing, and this listing is only for the Soft Screen. Two spare Soft Screens are included. The frame is clean. The glass surfaces are also clean, with no scratches or dirt that would affect the image. Accessories include a plastic case. Shipping will be via Yu-Packet Post. Shipping costs are the responsibility of the seller. There may be times when I am unavailable. I will try to include this information in my profile, so please check it. Please refrain from price negotiations. --- 52mm center focus filter, made by Kenko, with two lens glass elements included. - Brand: Kenko - Size: 52mm - Accessories: Lens filter body, 2 lens glass elements - Type: Center Focus Filter Thank you for viewing.
