● Metal, male-female type intermediate adapter ring. (I didn't know the official name.) ● The structure of this ring is the same as a step-up ring. (So it's male and female.) It's used when you want to attach a filter, etc., of the same size to the filter diameter size at the tip of a camera lens. ● It can be attached to any camera lens from any camera manufacturer if the filter diameter size matches. ● The numbers in the product title are written on the side of the ring, so please rest assured. 【 ※ Note 】 Please be aware that it is not "male to male" or "female to female." m(v_v)m ********************************* ↓↓ Common product description from here ↓↓ ■ If you can't find it!
