This is going to be a hell of a compact camera! We just got the specs via SAR and this is what the new camera can do:
20MP sensor (same as RX100/M2 models)
24-70mm f/1.8-2.8 lens
Built in View finder (SVGA OLED Tru-Finder 1440k dots)
Tiltable screen (180 degrees up)
Record in XAVC S format (Same format of the Sony A7s but with no 4K output option).
Almost same size and weight as the current RX100/M2 models.
I have been told all other specs are the same of the current RX100II model.
Price is said to be around 800-850 Euro in Europe. Should be around $800-850 in USA (US price is my guess)
This will be the best compact camera ever made!
