I received my Mavic back in October and after image softness frustration, I sent it back for service in February. After two months, I have a Mavic again but I still can't understand how to properly focus this thing. The replacement Mavic still feels like a lens misalignment because either the top left is out of focus, or the bottom right is out of focus.
If I do a focus stack in Photoshop of 3 images with 3 different focus points, it shows how the focus shifts from top left to bottom right. If the Mavic camera is pointed straight down on a flat surface, shouldn't everything be in focus on all 4 corners?
I can understand depth of field at f2.2 but I don't understand how one side of the frame (top to bottom) can be sharp while the other side is very soft.
Is this user error or did I receive another defective lens?
I agree. It still has the problem but it's also not the same Mavic. It's a new serial number and a replacement unit that was manufactured on March 10th. It's unfortunate they are still coming off the assembly line like this.
I'm using the GO4 app. After talking with support, reinstalling firmware, calibrating IMU, calibrating gimbal and resetting the camera, the results are still puzzling and suggests a lens hardware problem in this second Mavic too. If this tool http://djiserialdecoder.x10host.com/ is accurate, my first Mavic was manufactured Sept 21 2016 and the second was manufactured March 10 2017.
Left side in focus only.
Right side in focus only.
Here are some screenshots of the app with the red focus markings.
If I point the camera straight down, everything should be on a flat plain and in focus. A center focus minimizes the problem but it's still strong on the right side of the frame.
Few more examples.
Center focused with softness on edges. It can't be depth of field because it's top to bottom.

Hi Stephen, I'm sorry it's probably a hardware issue.
Did you contact our tech support to create a case for this aircraft?
Hi Mindy. Yes, it was sent back a couple days ago. Fingers crossed the 3rd one is ok and hoping this time it doesn't take another 52 days. I'm annoyed but have faith since I have friends with Mavics that work fine.
Interestingly, a neighbor had the same problem who also sent his back in February and received a replacement last week too. His new one works fine.
