Hi!,
      Just bought a Mavic Pro last Feb.2.My problem is focusing.Even in AF or Manual.just like other lenses in dslrs. If you put to infinity it should focus.but its not that i thought it should be. I tried the IMU Calib still i cant nail a focus. I watched several videos in youtube with ND Filter in bright sunny day and still they can get good focus and sharp images.

P.S. i used the NiSi ND 8/16 filter since its too sunny.

Do you put your ND filter on before or after turning on the Mavic?
Is the filter pushed in completely?

Just to verify, have you tried to reset the camera settings? Please try and check if the camera/filter is dusty, try to shoot without a filter, and check if the original pictures or videos on the SD card have the same issue. And you can provide me with some original videos for a further help. You can upload the files to Dropbox and paste the link here. Thank you.

This is in the FAQ:

2.When shooting in manual focus mode, my shots are blurred even when moving the slider all the way to infinite focus. Why?
The focus range of the Mavic is 0.5m to infinite. Slide along the bar until you reach a focus point. Sliding straight to infinite focus does not guarantee sharp focus.

As the Mavic will allow you to focus past infinity, you can't just set the slider all the way and expect things to be in focus. I turn on Focus Peaking to get feedback on what is in focus and it's a real useful feature. Hope this helps.

Should i remove first the filter while calibrating?because i always put the ND filter. And i didnt yet fly my MP without ND filter.

Reset the camera and take off the filter and calibrate the gimbal
