Source: Serious lurking on this forum.
Observation: Two of next year's camera bodies will allegedly get entirely new naming systems: the high MP, and the 7D successor.
Speculation: That's because they'll introduce Canon's new sensor technology. Probably 180nm instead of 500nm (on a side note, I'd love to know more specifics about what that means).
Question: If Canon does implement this tech in a 7D.2, could that APS-C camera produce lower noise at low ISO than current FF cameras?
I ask because I'm pretty invested in EF-S lenses but also very interested in a 6D. Low ISO IQ is the #1 consideration for me. Thanks for any thoughts or info!
There is no sign that Canon has invested money in a new sensor technology
What they can do is to move the ADC closer to the readout points and improving the signal path way.
If there are any improvements in the latest camera it is probably noise reduction and already in the raw file stage and in the red and blue channels.
Canon can not with their current technology make small circuit solutions that other manufacturers can do today, for example Sony, Omnivision Aptina etc.
