>>4318032Distant foliage and brown pine needles on browner ground is literally a CFA nightmare scenario. It's why landscape photography favors high res sensors even if you're not printing huge. If half your image is bryce bayer's worst nightmare, then it helps to have 4x more resolution than would normally be needed just to get a usable downsampled image by basically pixel binning bayer with extra steps.
On a B&W test chart, foveon/mono is slightly sharper. On most real subjects, no one could be assed to tell.
But if you have finely alternating combinations of green/blue/red, like tiny distant leaves against the sky, against brown (close to red) tree trunks, pine needles on the ground, etc, sensor go ACK
You also need a hilariously sharp lens because in that case the demosaicing algorithm misinterprets the lens blur too
