I have in problem in my Mavic pro.
it’s very difficult to set focus at night. If I set focus to infinity, I have not focus....
For example, the Litchi has setting calibration lens.
DJI go 4 has removed button “calibration again” why?
How I can do calibration, for setting to infinity?

Why not use auto focus , just touch the screen on a bright subject for focus

It is, indeed, tough to focus at night, but you can't rely on the infinity mark as it will actually be a bit past actual infinity -- turn on Focus Peaking and look at bright lights like Iannes suggests. FWIW, though, I haven't had much success myself with original Mavic Pro nighttime photography -- that AC really wants a lot of light.  

There's no such option like "lens calibration" for Mavic class UAV. This feature is offered only for Zenmuse X cameras with removable lenses of various brands.

Yes, but why DJI didn’t setting about calibrate lens in DJI GO4?
I have a alternative fly program LITCHI, it has a that setting for mavic pro.
If I did calibrate lens, focusing wheel to infinity set the hyperfocus  >50 to infinity. it is very convenient and practical.

Yes, but it is strange.
In the Litchi this functionality works good to the mavic pro (calibrate lens)

By the way, in Litchi the wheel scrolling is accompanied by clicks and has a numerical gradation.

Another reason for me to try out Litchi, which I've been meaning to do ever since I picked up my MP.
