Re: Reality?

The physical laws of optics and practical experience show increasing sensor (or film) resolution results in more image resolution - with any lens at any aperture.

More resolution at base ISO primarily involves smaller film grains or smaller pixels. At higher ISO's the efficiency of the process engine and the light receiving capacity at each pixel limit the resolution loss compared to base ISO.

There has been relatively recent internet myths (they are myths) that pixel density can negatively effect resolution, despite the physical laws of optics and actual photographic results confirming the opposite.

I got more resolution in images each time the grain size in 100 ISO slide film was reduced, and got more image resolution each time the pixel sizes were reduced going from D200 to D7100, and going from D3 to D800.

Producing good quality photographs, or being good at sport or art, involves a little more than buying appropriate equipment. Practice, some learning and perhaps natural talent often play a bigger role than the equipment in your hands.
