K&F Concept 52mm Variable ND Filter ND2-ND32 I am selling this because I no longer have the opportunity to use it. I hope you will find it useful. * There are noticeable signs of use around the filter frame. (e.g., see photo 5, the entire frame area is in this condition) Since it's been a while since I sold my lens, I can't confirm how it will look at this stage, so I'm selling it at a low price. When I was actually using it, there were no particular problems with the image quality. * There is some wear and tear on the frame. Please check the photos.
