Which lens (or which effective focal length) is most suitable for Drone deploy flights of buildings?
Edit:
Lenses available on the X7 are:
16mm (effective focal length 24mm)
24mm (effective focal length 35mm)
35mm (effective focal length 50mm)
50mm (effective focal length 75mm)
That’s a tough one, but I would vote for the 16mm. It has the FOV (70-75deg) closest to the majority of drones (75-85deg) that are currently being used for mapping. The others are way too narrow and you would have to fly quite a bit higher to get the same overlaps. If you going to have just one maybe the 24mm would be a better all around, but you would have to experience both to see what you like.
