I now only have an RX10 mk4 as my 'big camera' and an RX100 mk3 for my pocket camera.
I downsized from full frame Canon gear and the only thing I miss is the low light capabilities, because, although both the Sony cameras can shoot in very low light, the quality is just not there.
The Sony cameras also deliver awsome video, and whilst the RX10 is 4k, the RX100 is only up to 1080, so my next and hopefully last camera purchase will be the RX100 mk 7 which allows 4k and has a 200 zoom, but is still small enough for my pocket.
