If you only shoot RAW and D-Log and like to spend a lot of quality time in front of the computer, get a Pro.. If you do any shooting for a third party, get a Pro. If you shoot a lot under low light, get a Pro...
I LOVE the Zoom. I'm just a poke-around flyer. I actually like flying more than taking pictures. (Some flights I never use the camera).
I just started my fifth year of drone flying. For four years I flew with fixed focal length cameras. (a GoPro and the camera that comes on the original
Phantom 4). The variable focal length Zoom has opened up a whole new dimension in flying. I shoot 1080P/30 most of the time which gives me access to the 2X focal + 2X lossless digital zoom. It lets me do stuff I couldn't do before.
I can 'see' so much farther when I'm in the air.. For instance, I live in the country about 30 miles south of a larger city with 200-300 foot buildings in the downtown area. When zoomed at the horizon (96mm) I can clearly see the city skyline and make out the buildings. I can barely see it with my
Phantom 4. Everything is just too small.
It's also a great 'spy' craft. If you fly the Mavic near neighborhoods at 200 feet or lower people hear and see it. This sometimes creates bad will towards drones. I can overfly places at 400 feet and see clearly what's going on on the ground as if I was at 100 feet. At 400+ feet you can hear the Mavic from the ground if there isn't much ambient noise, but it's just a speck in the sky. Barely enough to notice unless you spend time looking up and searching the sky for it.
