RX100 IV tested at Dpreview. New Slow motion at 100, 250, 500 and 1000fps.

Dpreview (Click here) posted the full RX100m4 review. The camera gets an impressive 85% score and the Gold Award:

The RX100 IV gains some headline-grabbing features such as high frame rate and 4K video but it’s the smaller features that most impressed us. Continuous eye tracking, fast Raw burst modes with AF, and small user-interface changes have made the Mark IV the most responsive and enjoyable RX100 yet. It’s the most expensive in the series but is peerless in terms of capability.

And Mirrorlessons posted the slow motion test video at 100, 250, 500 and 1000fps with the RX100 IV:
