This is a set consisting of an 8x telephoto lens and clip for smartphones, featuring the "DIME" logo. It attaches to a smartphone with a clip, allowing you to photograph distant subjects. Focus is adjusted by turning the focus ring on the lens. It was once offered as a special appendix to the magazine "DIME." Depending on the smartphone, a black vignette may appear in the corners of the screen, but this can be adjusted using the smartphone's zoom function.
