This is a set of three 77mm step-up rings made by Kenko (made in Japan), with a soft filter case. ① 72mm to 77mm ② 55mm to 77mm ③ 49mm to 77mm With one 77mm lens filter, you can use it on lenses with 72mm, 55mm, and 49mm filter threads. I had prepared these but forgot and purchased filters for each size. I am selling these as I will not be using them. The soft filter case has been stored in my camera bag since purchase, so it is like new. This is a used item. We would appreciate it if you could refrain from returns, refunds, or complaints after purchase.
