My mavic certaintly doesn't do this in video, but are you really sure, that it's not the ND's fault? Could you upload some shots without the ND?
This is really interesting, because Mavic's lens definetely creates a very noticeable vignette, which you can see, if you edit raw DNG photos without lens corrections.
Most likely all Mavics have this kind of vignetting in raw DNG photos, but for jpegs and videos the internal processing removes the vignette by brightening the corners. That means, that the corners of the image (as I've noticed in my videos) are very noisy, because of the internal processing compensating for the vignette and lifting exposure.
If we could disable the internal vignette correction and use an optical vignette correction, like a specifically designed radially graduated Nd filter, that would improve the Mavic's image in the corners a lot.
But since DJI probably won't introduce a setting for disabling internal vignette correction, and ND like this would be useless. But your example is very interesting, since it kind of looks like the vignette hasn't been corrected. I would really like to see a video without any ND filter. |
