☆ Marumi's 100mm magnetic filter holder for M100, a Gradation ND 8 filter. ☆ Because it's magnetic, it's super easy to finely adjust the position (move the filter) to match the angle of view after attaching it! ☆ Once you use a magnetic type, you won't be able to use anything else. ☆ I used it for simultaneous shooting with two cameras, but I'm selling it because I only need one now. ※ Please note: As shown in photos 4 and 5, there are fine scratches within the red frame, so please be sure to check them. These scratches are on the filter, not the lens, and I have never felt they affected the photos. ◇ No comment purchase OK, please refrain from price negotiations. ◇ If there is a significant oversight that affects the value of the product, ★ please send a message ★ without rating the item.
