Thanks everyone for the input! What sebboh suggests makes a lot of sense; that the huge dynamic range makes it tempting to go a bit too far with the shadow lifting and highlight recovery. I'll keep it in mind the next time it occurs.

another issue with this particular photo is that it is split toned – highlights are sepia and shadows are selenium. i'm not sure exactly how lightroom deals with the transition point from light to shadow particularly with shadow recovery jacked up all the way...

That example from sebboh seemed to be because of stitching different sky tones, which isn't really an RX1 issue.
In-camera vignetting correction in a lot of cameras can be an issue, too. I leave mine off.
My apologies. I got confused.
Another thing to consider is that all RX1 (and A99/A77) raw files are compressed. They're essentially using the same compression as the old "cRAW" option on the A900, and it can be slightly lossy. If I remember correctly, the raws are compressed down into only 11 bits of tonal value, so that could cause this occasional issue when things are cranked in the raw converter.

I didn't know that, though I should have from owning the a900 (which offered a non lossy raw option). Sony really should be offering the option of a non lossy raw in addition to cRAW on all of their higher end cameras.

I'd imagine that the smaller files that Sony gets by using cRAW in the newer cameras allows them to use smaller buffers and whatnot while still maintaining fast frame rates. I've also read that using continuous shooting mode on the A99 means they use a 12 bit file that is compressed down, rather than the 14 bit file of single shot mode.

Sure would be nice to know if the 12 bit vs 14 bit in single shot vs continuous drive mode of the A99 was also the case with the RX1.
I suspect all this is academic though as I sort of doubt sebboh's posterization issue is due to this.

Oh, the A99 still compresses both the 12 bit and 14 bit files down to 11 bits, so it isn't any better in that regard.
I'm kind of wondering if this may be the issue, once you add jpeg compression on top of the built-in raw compression.

Well, 12 bit vs 14 bit in the raws makes no difference (as was fully explored a few years back) so I just figured that 1 extra bit might not matter. I could be wrong.
I really think his issue would have been there regardless due to how much cooking the file has gone through. Maxing out the shadow recovery alone might not do it but combined with other editing (split toning, possibly pushing one of the channels hard in the B&W conversion)...the only raws I have played with that can withstand those sort of extremes with subtle tonal transitions were from MF sensors.

I was having a little anxiety leaving my D800 home for a destination wedding in Maui. I am used to bringing lots of equipment, but I am glad left the big guns at home. The 35mm on the RX1 was wide enough for most cases!

Thanks for the link. Very interesting. The OP in that thread seemed to know his stuff. Maybe there is something to this being the issue. Dang, now I really wish we had a non-lossy raw format as an option.

for what it's worth the color version of the same shot where i didn't touch the shadows but pulled the highlights all the way back doesn't show any posterization.
