I agree with you completely, except that normally, the more experienced guy would show up with the
Mavic Air 2, or the
Mavic 2 Pro, or an
Inspire 2. It's very unlikely that he'd show up with a
Mini 2 or a Spark. I mean, come on, how lame would that be! Or in your scenario, he'd likely show up with the Sony a7R III. Now I'm not saying it's impossible that a professional would show up with his phone, after all, phone cameras are getting pretty great, but professionals usually have - and use - professional equipment. Professional also know that - like you said - if they show up with their phone, someone is likely to show up with something better. Consumers, usually have consumer equipment (In my personal opinion, things like the Mavic Mini and Spark). Now every now and then you'll see that rich beginner with the Red camera or whatever but it's not often.
