I have big pockets.
So do I, and that's a critical parameter, I think. Because it gives you the option of using an interchangeable-lens camera for walk-around shooting.
My current "pocket" camera is a Fuji X-E2 with Fuji's 27mm f/2.8 pancake lens attached. (The lens is a current product and the body is still available, both used and even new from some vendors.) The combination is essentially weightless on my shoulder, which is how I typically carry it, but it also fits into the larger pockets of several of the jackets that I own.
And when I'm wearing one of those jackets with big pockets, I usually drop the compact (and rather surprisingly excellent) 18-55mm kit zoom into one of them. If I need to go wider or narrower than the 27mm, it's a 30-second switch.
A few years ago, I made
this picture in Prague with the X-E2 and 18-55mm. It prints quite nicely at 18x22 inches, so I've never felt the need to upgrade to the higher-resolution X-E3. And, of course, the X-E2 also works fine with any of the other Fuji X lenses. (I currently also shoot with an X-T2 and a Nikon D800E.)
