I don't know if there are fewer dots per inch in the upper picture or what
Dots per inch (dpi) is a property of a printer. The metric has no relevance to viewing a picture on a screen.

Just as viewing an image on the screen has no relevance to the technical abilities of the lens that took it.

Not resolution, but total pixels projected onto a sensor.

The problem is there are fewer of those "best" pixels. Would you still insist the same if we used a FF-lens on a phone-size sensor?

Would you care to elaborate which step in my logic is faulty?
Your APSC body has a certain amount of pixels. It's the same regardless of which format lens you use. You could have your sensor seeing all of an APSC lens' image circle, or you could be cropping away half the FF lens' image. Either way, my K3 gathers 24 mpx worth of information.

These matters really aren't worth worrying about. Resolution and detail is a problem solved, for at least the past decade.

When we were selling images our best seller was a 10 MP Optio 90 image printed at 30x20.

Can you clarify what you mean by "captured resolution" ?
Is this the final IQ of the image after lens quality and sensor performance are combined?
I know its kind of loosy goosy term but the what the the combined resolution you are able to pull from both the lens and the sensor performance together

Nice one swanlefitte.
Looking back over the thread I feel angerdan's links (post #32) are interesting.
Nikkor AF-S 58mm f/1.4 G (FX) - Review / Test Report - Analysis
Nikkor AF-S 58mm f/1.4 G (DX) - Review / Test Report - Analysis
MTFs below
They really show the dulling influence of the pixel count on the end result of the image.
And if we look at the tamron 35 and the nikon 24 1.8 they show the same pattern
