Does anyone have a good tip for this, I shoot a fishing show, and both salt water and fresh water constantly get onto my lens, i use lens cloth and alcohol wipes, and i still have problems with fogging up, smudges taking forever to come clean. I need to be able to get as clean as possible as quick as possible. so i dont have to stop recording to clean it off quick. Is there something i can treat the lens with to repel water easier. Thanks everyone Darryl
