If you can live without a viewfinder then its a reasonable buy, its not pocketable though, a Sony RX100 Gen1 would give you that but has a smaller sensor. The lens is fine optically, but plastic bodied. AF speed acceptable but not zippy, moving objects will be painful to focus on, unless you can pre-focus.
I've had an X-A2 but found I prefer a viewfinder, and the screen was difficult to use in bright sunlight. It really depends what you want it for.
