The question was, do I use my DSLR (Canon 1Dx w/ 16-35mm f/2.8 II lens) or a DRONE (Mavic Pro) to shoot a group photo of 300 people?

I explain the setup and the results here:

Photo BELOW: Canon 1Dx, 16-35mm f/2.8 II @ 21mm, f/8, 1/200th, ISO 2000 

Photo BELOW: Canon 1Dx, 16-35mm f/2.8 II @ 19mm, f/8, 1/200th, ISO 2000

DJI Mavic Pro 12.35MP @ 4.73mm, f/2.2, 1/220th, IS 100

Conclusion:

The DSLR Photos was composed better because:

1. People were paying attention and looking at the camera

2. I was holding the camera straight and was at a good elevation

3. DSLR quality of the photo was sharper and more detailed.
