I am looking for the best rated filters for my M2P. I am leaning towards PGYTECH, but still doing my research. What's important to me is of course quality first, but I also need a filter which I could leave on the drone with gimbal cap/cover on. I do not want to remove the filter each time I use it. I would like to minimize that operation and save the lens treads from wear and tear. I've read that some of the filters will allow for this, albeit a tight fit and perhaps other filters that might becoming out soon - to address this issue of the gimbal cover. I need to know whats available now, that would fit my need. Thanks
