AIR2S Camera Focal length info for Panorama

[murph8857]

I am new to creating panoramas. The Hugin software I want to use is asking for the Focal length and Focal length multiplier. I believe the focal length is 22mm but not sure what the multiplier is. Thanks for any help

I believe the focal length is 22mm but not sure what the multiplier is.

The focal length is much less than 22mm, but I don't have an Air2S to check.
It's lens has a similar field of view (viewing angle) to that of a 22mm lens on a full frame 35mm camera.

If you check the metadata from one of your image files, that should have the actual focal length.
The multiplier is usually referred to as a crop factor and doesn't apply to your drone's camera.
