I don't know why people say that Canon ever uses the same sensor from camera to camera. Canon says they never do--they never just take sensors off one assembly line and plop them into two different camera models.
Canon ALWAYS claims "we have made improvements/changes" or "with an entirely new 18MP sensor" but these "new" versions of old sensors rarely (if ever?) have any measurable change in the real world.
They can make all the claims they want, but that 18MP sensor that was in the 7D etc. was in like 12 different models.
...that to put that 18MP sensor into the SL1, or Rebel, they have to alter the pin out, or some other electrical tweek, in my humble opinion does not mean they have come up with a "completely new sensor". It's B.S.
You can go from a Carter Thermoquad in one model, to a trio of Holley 2300 "Six Pack" in another, but it's still a Chrysler 440 c.i. engine. (and frankly, the differences in these "new" sensors are far less considerable than the "Six Pack" variation.)
I don't know what is going on with the EOS-R vs. 5D4 in this regard, but given Canon's track record, them stating "an entirely new sensor" that spec'ed out exactly like the 5D4 sensor, it would be easy to understand why the jaded among us would automatically assume same old same old again. what i NEVER would have thought, and still don't quite believe, is that Canon would have bothered to R.D. an "entirely new design" that performs WORSE than the one they put in the 5D4 3/4 years ago??!!??
Is it possible it's the electronics in the other chips? I just don't get it?
IMHO, the last time it was OBVIOUS, and measurable that a new sensor that seemed like it might be the same, was in fact "an entirely new sensor" was the 6MP CMOS in the 10D, vs. the 6MP CMOS in the 60D.
