Unless MR is misquoting Sigma, it is Sigma themselves that state that the SD sensor is equivalent to a 30 Megapixel Bayer sensor.

Which is at best, subjective.

(Which is 10 megapixels more than my 6D.)

Except that your 6D has real pixels, not an 'equivalent.'

Only because camera manufacturers have somehow got away with misusing the term "pixel." Each pixel on a Bayer sensor only captures a single color

http://en.wikipedia.org/wiki/Bayer_filter

It is a stretch to call a receptor that can only capture a single color a pixel.   When pixels in other devices (monitors) have true R, G, and B pixels (or at least RGB triplets.)   Pixels in images are R, G, and B.

Manufacturers of devices that use Bayer sensors should not have been able to use "pixel" the way that they do.  Among other reasons, it leads to overexpectation when looking at 100% crops.  On cameras that have Bayer sensors.
