Looking at images above (very good, so thank you) it reminds me to say that there is a fix to the lack of filter thread for the mighty (and very successful) RX100, with a magnetic fitting - here is a video that explains and exemplifies:

With the RX100 is it better to convert from RAW with DxO or with ACR?
I think DxO does lens corrections better than ACR, but other things not as well. There are no adjustment brushes or similar tools in DxO, for example (that I know of, anyway). One option is to use DxO for the lens corrections, and export to .dng format to finish in ACR. DxO has an option to open directly into Lightroom in fact, and it's really quite seamless to work that way. I haven't tried to open directly from DxO to PS, but maybe that's possible also.
Here are four images I took last weekend with the new camera (first time out). Super fast response time and seems to accurately focus in low light, pano feature is fun. Except the pano shot (jpg in camera then processed in LR4) the others were shot in RAW and processed in LR4.
