Been to Glenn Canyon National Park in Utah a few times. Been on the river and on the canyon rim. I can say, during summer, this is exactly the scene you will see. Beautiful place. Anyone here who is into landscape, Arizonia and Utah are must visit, even for a portrait shooter like me.
Even with markings on my lens, I still tend to just focus lock on a slightly further subject and do a preview. Of course if not a very bright day, preview also very difficult, so use smaller aperture for insurance.
anyway, for a wide lens, not much need to hyperfocus.
Why? It's pointless in this case. Never mind that the difference is so microscopic that the mechanical focusing tolerances are probably much larger than the difference between "infinity" and "hyperfocal" focusing.
