Right now, most cameras cannot resolve the full resolution of the chart (4000 L/PH), but the 24 MP D3X comes closest, and it's just an aliased mess. When we get cameras above 24 MP, we'll start to lose the ability to see how the aliasing artifacts look, but there's a long way to go before we'll lose the ability to determine the alias-free resolution. And even when that happens, this chart will still be useful for showing differences in contrast and aberrations, even if it can't show the ultimate limit in resolution.
