RX1R III vs Leica Q3: Does Sony's $5,100 Compact Justify Itself?

Five grand for a fixed-lens compact with decade-old battery tech sounds like a hard no. But the RX1R III isn't really competing with versatility, it's competing with a very specific kind of photographer who wants the smallest possible full-frame package and doesn't need the Swiss Army knife. The comparison against the Q3 is the right one to run, because these two cameras are chasing the same client: the travel shooter or street photographer who bills enough to justify carrying one beautiful, limiting tool. If the Sony wins on image quality but loses on usability, that's not a draw. That's a dealbreaker for most working photographers. Worth reading if you're actually considering either camera for paid work, safely ignorable if you're not already in this price bracket.
