Canon has quietly developed a "stacked" sensor for the upcoming R3. No one saw that coming.

Rumored megapixel count is over 50.

The so-called professional cameras seem to be bandwidth limited. The photos need to be processed and uploaded ASAP, which is why Canon isn't putting a 50mp sensor into the 1DXIII...

There might be a time when they do go beyond 20mp or so for the 1D series.

I'm definitely interested in whatever is the successor to the 5DSR/1DsIII. And that new 100mm macro with the defocus control.

If/when Sigma releases a 20mp FFF, I have no doubt that it will be comparable to a minimum 60mp Bayer sensor "full frame" camera.

The usual view is that a Foveon is roughly equal in resolution to a Bayer with 1.7 or 1.8 times as many pixels. Certainly not 3x.

To equal the fp L, a new Foveon would need at least 30 Megapixels. That would be, twice the area of the Merrill, with the same pixel pitch as the Merrill.
