There's a lot to be said for DJI making for an easy entry into aerial photography, but much more that I don't think is understood. Most going the DJI package route have shot their wad by the time they've used up their credit line or disposed of their disposable cash. Loss of GPS will mean loss of control and perhaps loss of an aircraft to a flyaway. The first crash and they will be severely hobbled, with no means, knowledge, or ability to repair. And they will crash.
The easy entrants will still for the most part be limited to the low end of the customer base. Those customers would have never looked to the higher professional levels to begin with. The cameras they will be carrying will for the most part be Go Pros and whatever type is included with the RTF package deal. The gimbals are slaved to the FC and any issue with the FC means there will be an issue with the gimbal. Even having 4k at their fingertips they can't shoot a truly good panoramic scene with those cameras, and there's still the editing that has to be performed to make a good still or video. It takes a long time to learn those skills, just as it requires a good eye developed through lots of experience to frame a subject to be photographed. ISO, f stop, depth of field, back lighting, how important could that stuff be anyway?
Then we have the accidents that are inevitable when a large group of amateurs elect to become instant professionals. Those that play by the rules or responsibility will be insured for injury and liability but the vast majority will not. A couple of injury accidents will encourage civil laws requiring liability insurance for commercial operators. People employing commercial operators will soon start to require certificates of insurance naming them as additional insured and the fly by nights will slink away from the exposure. Businesses that employ commercial operators or fly their own stuff will quickly recognize their liability, both in increased Workman's Comp rates and company liability and return to contracting out to avoid the direct liability.
In the short term the budget shoots will see a lot of influence from the entry level, ready to fly "professionals" but I think that will even out fairly quickly. The real professionals that know what they are doing will be sidelined only long enough for the customers to see the product quality they are receiving, or not receiving, from the DJI crowd and decide they would rather set up and pay just once to get a good job instead of several times. We should also remember that DJI is in it for DJI, not the user, and when things go bad their users have consistently been left hanging.
