● Metal, male-female, intermediate adapter ring. (I'm not quite sure of the official name.) ● The structure of this ring is the same as a step-up ring. (Therefore, it's male and female.) It's used when you want to attach a filter, etc., of the same size to the filter thread size at the tip of a camera lens. ● It can be attached to camera lenses from any camera manufacturer as long as the filter thread size matches. ● The numbers from 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 Starts Here ↓↓ ■ If you can't find something, or if you're purchasing multiple items, I will create a "dedicated page" with a discount for shipping, so please feel free to comment. ■ There may be some changes to the design.
