This is a Sony Carl Zeiss MC Protector filter, 49mm. I purchased it new from the Sony Store some time ago, but I am selling it because I sold the lens. It has been used very little and the exterior is clean, but there is a small scratch on the lens. It's about 1mm in size. I tried to photograph it, but it's such a tiny scratch that I couldn't capture it well. I don't think it will affect your photos, but please make your own judgment. Other than that, it's clean, and there are no visible scratches on the screw threads. (Please understand that there may be extremely minor scratches that I have overlooked) I have lost the filter case and original box. Please consider that the item is only the filter itself. Thank you.
