focal length when creating map

My Yuneec CGO3+ does not record the focal length EXIF tag.  I've added it via exiftool with no issue, but wonder if it pertains to the actual focal length of the lens of the camera (14mm), or does MME need the "35mm equivalent"?  If so, I'll need to find how to convert it.  Just wanted to know what MME is asking for.

Thank you!

We take the presented focal length value as a starting point. The 14mm value is what should be used though. Your real focal length is probably more like 4 or 5 mm though. 14mm is probably the 35mm equivalent.
