What exactly is Camera/Lens optimization service? How good is this? Can someone elaborate on this? I recently happened to read this in another forum (phantompilots.com). I am really curious to know more on this topic.

Hello Emma, welcome to the Mavic forum. I think you're looking for the Phantom forum.

I m guessing it will be something with regard to aligning the camera lense with the sensor. So ideally the image is sharp across the frame, and not left (or right side) being blurry.
