77mm Kenko PRO1 Digital Filter Pro Softon-A (W) Used I bought this a long time ago for astrophotography, but I'm selling it because I've changed lenses and don't use it anymore. As the photos show, the case is cracked. There are no scratches on the filter itself, and I don't think it will affect the photos, but I can't be certain as I'm not a professional. I've used it a few times. Please understand that this is a used item before purchasing. Returns are not accepted as they can cause problems.
