Okay, this is strange!

I have been using Polarpro filters for a while now without any problems. But now it seems as everytime I attach one of the, the camera goes out of focus! I have made sure they are clean so that is not the problem.

Whenever I remove the filter again, the camera can focus again.

It was bright and sunny and without filter the exposure time was 1/1309 sec. So I could definitly use a filter here!

Any hints?

Should mention that I have a Mavic Pro!

Well, seemed that I should just uninstall and reinstall DJI Go 4!

Ole, did the issue resolve? Have you tried other filters? If the issue persists, could you please provide me with a video of this case, a picture of the filters that you're using and the firmware info of your drone? You can check it on General Settings, About. Thank you.

Thor, it did solve my issue.

FYI I tried Polar Pro ND 8, 16 and 32 which all caused the videos to be out of focus.

When pressing my screen to set the focus (using iPad mini 4) I could see for a short second that the video was in focus but then it went back to be unfocused again.

If the problem comes back, I will save some of the videos and inform you of my version of the firmware (but it should be the newest)

I have the vivid filters of polarpro, the focus is fine at me, no issues. (go 4.1.22), fw 01.04. 0100
