Right! And this is why the image looks as good with the regular Summicron 50.

Every time I looked at a pair of images on-screen presented at the same image scale, there came a point in progressive enlargement where I would see more native resolution in the image from the smaller sensor. This continued, as I recall, until somewhere between the 1”-class 20-MPx sensor and the 4 x 6-mm, 12-MPx P&S sensor. Since the smallest sensor, with 12 MPx, is the equivalent of a small section (1/25) of a FF sensor with 300 MPx, I concluded that it would take a FF sensor of well over 100 MPx to match the native resolution of even the zoom on the P&S camera (though, to be fair, I think where high-end lenses surpass mass-market ones is in the zones well off-axis, and at wide apertures).

If a camera with a fixed WA lens had a FF 200-MPx sensor and a digital zoom function, and an EVF, it would have the same capabilities as a big FF DSLR with a 24-120 zoom—even with a linear 1/5 crop, equivalent to a 5x zoom, it would still give an 8-MPx image file, quite adequate for most purposes. Think Leica Q with a denser sensor and a zoom lever.
