Even pro photographers won't really utilise it in a professional shooting. It's kinda like a gadget that seem interesting to camera enthusiasts but has poor real use cases. I worked with Sony cameras and interface is very familiar but shooting manual on phone is not enjoyable because it's done with touch screen and no viewfinder. Without dedicated tactile buttons and wheels for shutter / aperture or focus and zoom It's just not replacement for the camera. It is a nice concept of the benefits of having android in an actual camera.
The benefit of shooting with phone is quick return rate but if you need to waste a ton of time in manual because auto and ai does subpar job then what is the point if you can just use camera and have it paired with phone for publishing. The other benefit is convenience of having it with you at all times and it's small form factor which in professional setting doesn't mean anything and for hobby or family moments when I wanna capture something and don't have my equipment with me I will just use auto.
Tbh Sony phones just feel like beta test on how to integrate android into their cameras in future. That is the only reason I can see their niche focus making sense.
I can't believe I played a black flag that is over 10 years old and is better in most ways, sometimes even in graphics.
