Mavic 2 Zoom controller == If I am flying in tight places, around trees, etc., the initial stick movement produces little change then it rapidly begins to produce more change then I would like. How can I set this for a smoother ramp up from 0?

Hi, thanks for the inquiry. The remote controller sticks can be modified using the DJI Go 4 app to apply your prepared settings. Hopefully, our valued DJI Forum members would provide the best recommendation that you may need in regard to this matter. Please see the screenshot below for your reference. Thank you for your support.

You can always switch your controller to "T" or tripod mode.  This will reduce the stick input speed and give you more controlled slow movement.

You might also try some of the settings suggested in this video:

you can add expo to your sticks if you find them too sensitive and that can be done in the DJI GO 4 App in the settings menu..
