Here's a re=post that I slightly modified from an earlier post I found on the forum from july this yr.

THIS IS A MAJOR PROBLEM - That seems like there should be a simple fix.
Obviously only a problem for video footage - not stills.
I'm not sure why this topic isn't discussed more, but the auto exposure function on the Vision 2+ camera renders most shots useless, especially when the camera is toward the sun within 90 degrees and contrast between the sky and and other white or dark objects pass though the scene. I've shot in many locations, attempting to record professional images, and continually experience poor results with instant auto exposure shifts or image pixelation. These shifts and flickers do not show up on the monitor, so we are not able to determine there's a problem on location unless we stop and watch every shot, which is just not possible when doing work on the move.
I understand this is not considered a professional camera system, but can't we expect better camera control. Does anyone have the skills and know-how to hack the firmware and turn off this setting? We will pay for it. Will DJI offer this option soon???
Seems like a simple firmware update to the camera could handle this?????? If this auto iris problem could be solved, the shots during a flt would be mostly useable vs only a few small sections of footage usable that I'm currently experiencing.
Here are a few raw sample clips at 30fps that show the flicker and adjustment , and MOSTLY exposure shifts. The footage contains great sequences that are unusable...
I have tested ISO in auto and setting it manually. WB AUTO and manual. Exposure 0 and -0.3. focus settings using all three. and as far as the auto iris issue - and till get the same result in all of these tests as far as shifting is concerned.
Two questions - anybody know of a fix to turn off the auto iris on the DJI camera? and if not how about a plug in or other work around in FCP X?
