This is a special filter that allows you to take five shots of a single subject. With the narrow-field type, the central image area appears narrower. The actual appearance varies depending on factors such as the focal length of the lens. An example is shown at the end of the images. This product is an old item that is already discontinued, so there may be minor scratches, dirt, and coating discoloration that do not appear in the product images. The resolution will inherently decrease when using a Mirage filter, so this shouldn't be a major issue, but please refrain from purchasing if you are concerned about minor details.
