Want to buy ND filter set but can not unscrew UV filter from my new phantom 4 pro camera. Assume counterclockwise direction to unscrew but afraid to use any more force than I'm using for fear of breaking something. Anyone else running into this problem?

Should unscrew without too much pressure. I have read that putting a rubber band on it for better grip works.

Used a rubber pad for unscrewing jar lids and worked perfectly. Thanks!

Mine was on really tight (from the factory).  Held onto the camera and unscrewed with a little extra force (counter clockwise) and it did come off.
