● 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. 【※Caution】 Please note 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! or when purchasing multiple products, we will create a "dedicated page" with a discount on shipping, so please feel free to comment. ■ Some design changes may occur.
