Let me start off by saying I love the machinery, the Mavic is an absolute beast of a drone, never dissapoints me with any of its functions only the camera, these are some test footage.I really have to get this fixed as I have several trips planned and want to get as good footage as possible, I'd rather not send it in but if the camera is defective I guess I have no choice.

PS. Sometimes I see that the right side is quite blurry, is it only me?

Seems a common QA issue with them.  Most likely the lens isnt exactly parallel to the sensor.  Mine is soft on the left to the extent i have to crop about 10% off the left edge for pictures.

Forgot to say, is this normal or should the image be better? Is there anything I can do or is the best option to send it in for repair?

What about resetting the camera settings? I had forwarded your video to the engineers to look into, will get back to you once I heard from them. Thanks for your patience.

I sometimes notice a similar effect. I have noticed that if I click on the right side of the image when focusing then the whole image is properly focused, while if I click on the left side, sometimes the right corner gets off. Try the trick.

Fwiw I'm not seeing any appreciable difference between the right and left sides in focus in your last example vid (haven't looked at the first two). You would expect the center to be the sharpest and edges to be somewhat less so, but these seem reasonably consistent.

A good test to check for decentering is to hover in front of a well-lit brick wall, preferably with the sun at your back, carefully frame your shot so the Mavic is perpendicular to the wall, take a few pics and check those for corner and edge anomalies.

Hi, I don't think that's a defective camera in terms of noise. Firstly please note that LOG footage increases dynamic range at the cost of visually increasing noise. Meanwhile, if you shoot complex scenes with very fine and randomly moving details, it is impossible to fit everything in the H.264 stream and some details are discarded by the encoder, which repeats every 8 frames. This may result in a flicking look.

Recently in a firmware update we slightly adjusted gamma which may induce a little bit difference in noise. Not sure if that's the tiny difference that you are looking at. If yes, switching to "vivid" color can do some help. More details below:

What problem did you encounter? May we have more details? Is that convenient to post the original footage here for further analysis?
