I feel like an idiot. Had my phantom for about 2 weeks now and I didn't realize that the stock camera has a pre-installed UV filter. I removed the little clear peel-off piece and thought I was good to go. I searched and see that there have been posts on this before, but I missed them so I'm guessing other people have too. The filter is on fairly tight so give it a solid twist and it'll come off. I found it easiest to turn my phantom upside down. I haven't done any tests yet but I'd imagine the image quality is better with the UV filter off, I know the UV filters on my DSLR have only degraded image quality so I never use them. Hope this helps someone!
