Hi all. I have the Polar Pro Shutter collection and I have to say I was a little surprised that some have had trouble installing and removing them. But I have one that seems to take no effort at all to install and remove. In fact after one flight I noticed it was actually starting to work itself off of the camera! I know it was on all the way at takeoff because the gimball tested fine at startup. Now Im worried about tilting the camera down for fear of loosing the filter. I was considering trying to maybe give it a squeeze but I dont want to bend it out of round so it wont fit or even worse break or pop the glass out. Anybody else had these kind of issues with these?
