I was modifying my P3P and what a pain this morning. I put the rubber bands around it and no slip but no go with the fingers, so I tried using small vice grips on the lens cap because that worked last time but this time the pliers slipped on the rubber band and no go. I can't believe that I actually had to put a crescent wrench on the camera with the vice grips on the lens cap edge to get it to move; it worked as always but this time... Because I had the rubber band wrapped twice around it and it was still slipping, I clamped a bit harder on the vice grips and put a chip in the lens cap glass. So I wanted to mention this because - If it's tight enough to need to use a set of pliers, then don't use a rubber band also. The rubber band actually took power from the pliers and had me adding tension that wasn't needed between the teeth and the rubber band. If it was metal to plastic, the teeth would have just dug in enough on the sides to open it with no damage. The camera is fine and now takes my screw on Rainbowers filters that I truly love, but man this cap was was on ridiculously tight.
The other thing that I noticed today was after I screwed my extra lens cap on finger tight, I grabbed it in the same place, top and bottom and it was stuck tight on there again. I ended up re-positioning my fingers on the sides and it spun right off. So I put it back on and tried top and bottom grip again and noticed that it gave in a little and so the top/ bottom finger grip was actually locking it harder in place.
So when unscrewing the lens cap, finger placement is important because it came right off just by having my fingers in the right place on the sides of the DJI lens cap.
