Confirmed via trusted source: Sony 1 inch sensor used by Panasonic (and likely by other companies too).

The recently announced Panasonic FZ-1000 did shake up the industry by offering a tremendous zoom range and 4K recording in a sub $1,000 package.

And according to our sources the Panasonic is the first non-Sony camera using the Sony RX100m3 1 inch sensor. The source also said the sensor will be sold to other companies too (likely Fuji and Samsung coming as next).

It’s likely that Sony cares more about selling sensors (and leading the industry in that segment) than protecting their own RX camera range. And actually that’s a good news :)
