You don't have to cart around a big-ass DSLR with multi-pound lenses. My pen-f (2016) runs circles around an iphone pro, and it's pretty small and light for a "real" camera (it can fit in my coat pocket).
> Cameras usually take longer to start and get ready to take a shot (or run out of battery sooner if you keep them on all the time) and have slower autofocus.
This is not true, especially if we're talking about DSLRs (as opposed to mirrorless). I used to have a Canon 40D. I never turned it off. It would stay "on" in the bag for however long I didn't use it. It consumed next to nothing when in "sleep" mode, but came out of it ready to shoot at the touch of a button. Autofocus was plenty fast, too. Ditto for a friend's Sony A700 (same vintage APS-C DSLR). I understand current mirrorless cameras have much better autofocus, even the mid-range ones.
Even my pen-f (mirrorless) wakes up or turns on much quicker than you can slide around your finger on an iphone. Autofocus isn't great in low-light, though.
