A new rumor floating around the web says that Canon is going to use Sony multi-layer sensors on two upcoming professional cameras. Myself as well as Northlight both received emails disputing this claim and that Canon will definitely continue to use Canon designed and manufacturers sensors in their DSLRs for the foreseeable future. Canon has used Sony sensors in the past with compact cameras, and most recently in the PowerShot G7 X.
Northlight points out and summarizes a recent Canon interview with DPR.
Q: Canon released two cameras at Photokina – the EOS 7D Mark II and PowerShot G7X. One thing we’ve learned is that the sensor in the G7X is not made by Canon. Does this represent a new philosophy at Canon?
A: We select the best sensor, whoever the manufacturer is. That’s our policy.
“As yet I've seen nothing to suggest that Canon's choice of (small) sensors for the compact market will be reflected in their pro kit. The comparison with Nikon using Sony manufactured sensors (with Nikon design input) is an easy one to make, but misses the point that Nikon is primarily a camera company, whilst Canon isn't, any more than Sony is.”
A commenter also mentioned Dual Pixel AF, which is a big part of Canon's marketing for sensors.
