This is the KANI 150mm square filter holder set HT105 Ⅱ. The adapter rings are compatible with the SONY FE 12-24mm F4G and Fujinon XF 8-16mm F2.8 ultra-wide-angle lenses. Two square filters can be attached. (Can three be attached with the included adapter?) I haven't tried it, so I can't guarantee it. It has been used a few times, so there are no scratches. (The current market price is about ¥23,000.) I would like to sell it to someone who understands that it is a used item. I am also selling ① KANI 150mm square PLC polarizing filter and ② 150mm square filter LAOWA 9mm adapter ring at the same time. Please take a look if you are interested. Thank you for reading to the end.
