My sony rx100 came back to me finally. They exchanged two parts of the lenses with all shutter and stabilization. I wonder how much more this little guy will withstand me and my travels. They send me protocol with "equipment state". And it goes as follows:
"crack and deformation of the upper housing, abrasions on the camera ring and housing, scratches on the lower housing, crack on the lower screw on the left side and on the lower housing near the card slot, slightly unsealed housing on the right side, scratches on the display, cracked LCD glass". It means "used by a woman" :D
So I think it's time for standard sunset from my balcony. And I have a feeling that this repair hasn't been fully successful, I was used to better photo quality. But maybe I have to change the settings as the camera was totally reset.
