I have tried each vesion of the RX100 since Mk2 - I would not buy a camera without a viewfinder. Unfortunately I wear glasses and when I use the RX100 vf it pops in and goes out of focus. I looked at the Panasonic but not happy with the lens speed to get that 10x range which I don't need for a go-everywhere camera (would take my X-T2). I went for the larger sensor of a Fuji X100T, couldn't justify the cost of X100F for the use it would get, there are p/ex deals on the X100/S/T so there are a good few around. I know it is only a fixed prime lens but I move my feet (or crop) to get the extra reach.
Each to their own, we all need to make different compromises.
