Sony RX100 new firmware available.
Yes for the oldest model !!!
At last Sony has solved the Steadyshot problem.
I've just downloaded the big file and installed the firmware.
Not as easy as Canon procedure, but not too difficult, just pay attention to remove memory card and choose the good USB function.
It takes about 10 minutes, so you need a full charged battery.
Now the steadyshot appears to be more effective.
Have a Nice Day.
