yah its the main reason why go pro went from the hero 7 to the hero 8 design of non removal front lens glass to being non removable. It was because to many people complianed of fog or condensation on the inside of the front glast and the camera lens itself. All it takes is the slightest of water moisture to fog a part of the lens. This can eaily happen too if you take the lens off in a air condition room or building or house and then go outside in a warm sunny outdoor place. The warm outdoors heats up that cool moisture and you get that foggy moisture on the inside of the protective lens cover.
