Real estate agents, industrial photographers, people who make money affiliate marketing, maintaining a (whatever) review channel on YouTube, journalists, heck even sales or running a small business, lots of professional use cases. The difference between good and great is the little things.
The photos I see on real estate listings are horrendously compressed and have a potato-like quality. I have no idea if they were taken 15 years ago on a $10 point and shoot or on a brand new professional DSLR. Only thing you can sometimes tell is that they used a wide-angle lens.
In my experience (Sydney, Australia) they tend to get professionals to shoot with a quality DSLR, then they get pimple-faced Photoshop jockeys to flatten the dynamics and punch in a fake blue sky.
This new extra-wide camera is interesting as it's fairly rare for a consumer-targeted camera to exceed a 24mm (FFE) focal length. Even in expensive professional lenses, getting to 13mm (FFE) is fairly unusual. Most ultra-wide glass stops at 16mm.
Or you know... bring a camera and be professional.
The idea that apple needs an extra $300 dollars to fit that into my phone, maybe i'll just get two pixel 3s. Or a nice point and shoot.
The 'bare minimum' that the consumer will accept vs 'the average feature set expected' vs 'lets sprinkle in some unicorn dust and charge people up the wazoo' model is getting a little old. Its why I have iPhone 6s, 7s, still in the fleet of devices I support. The consumer and businesses are simply tired of this bs.
