Use a Shoe to Remove Stuck Lens Filters
Here’s a quick tip for if you ever have a hard time removing a lens filter from a lens (e.g. when it’s damaged): use a shoe. Simply take any shoe with a grippy flat bottom, press it firmly against the filter, and then turn it. It’s a super simple technique that should work every time unless the threads on the lens itself are badly damaged.
Thanks for the tip, Luke!
