Yes, I've just seen the Preview.
OK the new RX100MKII seems to be better in low light (faster focus), has a tilting screen and a hotshoe for flash.
But sadly, the announced increase in sensitivity is not real, now it start @ISO160, ISO80 not more available, and ISO100, 125 are expanded modes !
Combined that with the fact that max. speed is only 1/2000S and no ND filter, I'm very deceived !!
And the official price is even higher than the RX100.
Have a Nice Day.
