Kenko Center Image 55mm filter. This product is discontinued. For details on its effects, please refer to the manufacturer's website below: https://www.kenko-tokina.co.jp/imaging/filter/soft/4961607352335.html This is an interchangeable filter that allows you to choose between a "sand screen" that sharpens the center image and a "soft screen" that creates a soft focus effect. It's a rare type of filter where you set either glass between the two frames and secure it with threads. The frames are clean. The glass surfaces are also clean, with no scratches or dirt that would interfere with the images. Accessories include a plastic case. It will be shipped 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 these dates in my profile, so please check there. Please refrain from price negotiations. This is a 55mm center focus filter that allows you to take photos with an emphasized center. - Brand: Kenko - Model Name: CENTER IMAGE - Size: 55 mm - Type: Center Focus Filter Thank you for looking.
