I usually take one of my cameras with me when exploring in new areas. My bigger one has an 80X zoom lens, but is bigger and heavier than my smaller more basic camera, but in addition to the higher power zoom it has more features. So it all comes down to weight, and many times my smaller camera wins out. I only use my cell phone camera if I'm out local and don't have an actual camera with me.
I've never been much for video, but I certainly see some advantages to that when coupled to a higher-end drone -- I wouldn't mind having one of those eventually, as I'm pretty good at spotting things from the air.
