That’s really unexpected as I thought Fuji would keep using their X-Trans sensor. But Fujirumors now reports that the upcoming Fuji X-PRO 2 could use the same A7000 sensor! The X-PRO 2 camera release got delayed to 2016 and they speculate the reason behind this is the A7000 launch delay. Sony allows competitor to use some selected sensors six months only after the sensor gets officially used on a Sony camera.
