About 1.4 MP. If you zoom in, what you see are the actual pixels that Photoshop produced by the RAW interpretation and JPEG conversion, what many of us call 100% crop.This is certainly finely detailed. So this is a 1 megapixel cropped shot? of the 102 of entire sensor, give or take a few I'd assume.
"Multi-shot 400MP mode for static subjects" what is this feature? I just was looking at it on a spec sheet. Some sort of lateral shift of adjacent pixel clusters electronically to achieve more density? Like a frame offset up, down, left and right?
I'm fairly sure the 400 MP mode is done by shifting the internal stabilization mechanism. By "static subject" they aren't kidding. It is useless for landscapes on a still day. Trees move around. Maybe product photography in a studio using electronic shutter and a remote app to fire. I doubt I will ever try it out. Maybe if I ever get a macro lens for it or adapt my Canon, that might be fun to try.
