This is a set of a Nikon circular polarizing filter 52mm and a hood HN-12 that can be used with it. The hood consists of two parts, and when using standard to wide-angle lenses, you remove the front part. Vignetting will occur with lenses wider than 35mm. The circular polarizing filter and HN-12 in this listing can be used together, but please note that they are not compatible with the circular polarizing filter II 52mm and HN-12.
