I still shoot with interchangeable lens cameras (both Fujifilm and Canon) but I do use my iPhone more and more of the time. On a recent trip to Europe, I had both my Fujifilm with a couple of lenses and my iPhone X. Looking through my photos on Flickr, there are some that I obviously took with the XE-3 given the low light conditions. But for many of the rest of my edited/curated photos, I couldn't have told you which camera I used without looking at the metadata. Probably if I blew things up big enough and really examined the fine detail, but not with casual viewing at normal sizes.
