Here's my current take, although I don't know where I fit in the demographic(s). I (strictly amateur) walked around/traveled first with various 35mm cameras, and then with a 35mm camera and lenses, winder, film, etc. Actually took a holiday from photography for some years after getting tired of lugging the kit around. Digital came around and after trying my hand at printing, ripped out the darkroom and moved forward. After close to ten years I once again found myself lugging a pretty heavy (APSC) camera and a few lenses around. Have mostly cut that back to the camera and one lens, either prime or zoom. Just came back from a three week trip (photography secondary) where I carried one camera, a Fuji X100T. I bought this camera because it had an APSC sized sensor, I liked the form factor and was curious about the Xtrans sensor. About an hour ago I printed some of the pictures that I took on the trip and am very pleased with results. Laying aside the camera's quirks and the fact that I'm not used to the fixed, wider focal length (purposely didn't want to buy into another system..yet), I am very happy with the combination of camera size and picture quality. As far as the demographics go, I am over 70 and the next camera I buy, will most definitely be mirrorless.
