I used it with a Panasonic power zoom lens. It seems to be adjustable from ND2 to 400. There is some feeling of use. There are no scratches on the lens, but there was cloudiness inside the filter, so I disassembled it with a spanner wrench and cleaned it. There is no grease loss. There is no problem in using it, but since it has been disassembled and cleaned, it is treated as junk. It supports a filter diameter of 37mm. Please use it between MIN and MAX. Exceeding the range may cause color balance distortion or X-mura. As a bonus, I will include a 37mm UV filter with dirt. I wiped it with a lens cloth, but there is dirt that cannot be removed, so please use it for old lenses, film camera lenses, research, or modification. Free shipping, shipped via Yu-Packet Post Mini. *Basically, we will ship within 2-3 days, but we do not ship during Golden Week and on weekends and holidays, so please understand.
