Maybe I'm the last to notice, but it seems like the new compact Canon G7X uses a BSI CMOS from Sony. I don't think Canon has actually confirmed that it is Sony, but they've said it's not an in-house sensor and the data looks very very similar to that of RX-100 series. In other words, it's highly likely that it is a Sony sensor.
I thought Canon only used Canon sensors in their cameras, but perhaps it has been different in the compact range? If not, maybe this is a sign that maybe Canon will consider using a Sony sensor to make a competing offer in the high MP DSLR niche, something many Canon users badly want since day one of the D800.
I'd much rather see Canon use a Sony sensor in this type of camera. Sony's Exmor sensor is class-leading by a margin when it comes to base ISO high MP image quality, while Canon has become known to be worst with lower DR and pattern noise at base ISO.
The D800 was released in early 2012 and we're now approaching late 2014 and Canon has not been able to come up with a competing offer. Rather than waiting for their inhouse sensor technology to catch up, maybe it's time to bridge the gap by getting a Sony sensor just like everyone else is doing?
