Might anyone have a used SONY VF-DCPL1 Drop-in Circular Polarizing Filter for FE / 600mm f/4. After cleaning I guess I didn't lock it in and now it's gone don't want to spend over 500 bucks for a new one. I have this posted at buy and sell also. Reach out if you can help. Ill take down the post if its not appropriate for the forum.
