☆ Marumi 100mm magnetic filter holder M100 dedicated Circular PL polarizing filter ☆ Once attached to the filter holder, it is very easy to use, with adjustments made using the rotating knob at the bottom of the holder. ※ Please note As shown in the second photo, there are fine scratches within the red frame, so please be sure to check. I have used it for many years, but I have never felt any impact on my photography. I used it for simultaneous shooting with two cameras, but I no longer need it, so I am selling it. ◇ No purchase comments are necessary, and please refrain from price negotiations. ◇ If there is a significant oversight in the product confirmation that affects its value, please ★send a message without rating the item★.
