Here's an image with 100% crops taken with a multishot back in microstep mode for comparison since I was curious. The pixel count (10880 x 8160 but in true color) is similar to a single shot of the Aptus 12
Eric, a 22MP multi-shot camera does not give 88MP, and it certainly does not magically give a 10880x8160 image from a 5440x4080 sensor; the sensor does not have that spatial resolution. What it gives is 22MP, with each pixel of very high quality due to being based on two green, one red, and one blue measurement. All industry standards for sensors rightly count pixels as locations on the sensor, and then distinguish the amount of information at each location.
For example, the official CIPA(?) designation for the new Sigma/Foveon sensor is "15.36MPx3", meaning "15.36MP, each with three color values", not (15.36x3)MP = 46MP. Even Foveon acknowledges in its technical papers that by measuring all three primary colors at each location, its X3 sensors give roughly the resolution of a Bayer CFA sensor of
twice the pixel count, not thrice (or in this case four times) the pixel count. (Sigma's marketing department then ignores what its own Foveon division engineers say! Pity, because even the truth probably gives its new 15MPx3 sensor distinctly better resolution than any current APS-C rival, and probably better resolution than any current 35mm format sensor.)
But 39MP multi-shot vs 80MP single shot might be an interesting and close comparison.
