The DJI Air 2S comes stock without a lens cover or just an open frame and I was worried about protecting the glass.
During my research before purchasing my first drone, I read the Air 2S does not have a aperture adjustment and uses shutter speed to compensate for exposure. Each of these Neutral Density filters or ND filter provides for increasing less light to the camera as the ND value increases or from 1/8 to 1/64 the amount of light. An online influencer recommended in his video to use a polarized filter to limit the light into the camera on bright days and more importantly as a lens protector and to provide glare reduction with polarization.
I obtained this polarized set and did a test flight for each one and compared to the unfiltered lens or as a stock Air 2S. Upon inspection they are quality products and fit on the Air 2S camera with just a small twist to lock in place
Attached is a video showing the unfiltered camera and then as a comparison each of the 4 different filters.
I'm not a videophile and to my eye all the videos looked excellent. From no filter to each of the filters I could discern no color difference or video acuity between them. All the images looked excellent.
I did see one difference however. Ive also read that some videographers like to use a filter in order to slow the effective shutter speed of the camera with more light attenuating filters and provide motion blur in the video. I did see motion blur especially with the ND 32 and ND 64 causing a blurring effect when the camera was panned.

Conclusion: For me Ill just add a filter for the polarization and to protect the camera lens. But I found that each of the filters was excellent in maintaining the video quality and providing motion-blur.
