I'm not sure of the official product name, so I've written this product name. Please understand. This product allows you to select one of two included filters with different effects and insert it into the filter frame for use. I purchased it but never used it, and it has been stored at home. A plastic case is included, but there is no outer packaging. The mini slatted board shown in the photo is not included with the product. **Brand Reliability** Kenko is a brand known for high-quality camera accessories. This filter is a reliable choice for professional photographers and enthusiasts. **Filter Features** The center focus filter emphasizes the center of the image and blurs the periphery. This allows you to highlight the subject and is ideal for creating unique art pieces. **Size Compatibility** The 52mm size is compatible with various lenses and can be used with many camera systems. This allows you to utilize it in a wide range of shooting scenarios. - Brand: Kenko - Size: 52mm - Type: Center Focus Filter Thank you for viewing.
