Yes this is the core problem. Smartphones are taking over in many sectors of photography. This weekend I was in a 3 days music festival and I seen the usual photographers, old friends, lugging around tones of gear, huge bags, stabilisators ... they were sweating a lot, they didn't enjoyed the moment at all. I was here to work for a music media and I decided to take my IPhone only. Guess what ? My pics are ok and the videos awesome. I made the coverage almost in direct, sending pics and videos imediatelly. The thing is that the audience for pictures and video (images contents) is young. This audience is between 12 to 35 and they are used to have thing very quickly, do not care that much about pixel perfect quality. They need to occupy their minds with things all the time.
The phone will not make better pictures than a good FF with good lenses, especially for concert, but the transition is here and I see all advantages of it. Especially when I get paid to have fun while my friend get paid to suffer
