Should I focus at the hyperfocal distance or at infinity for landscapes?
Focus at the hyperfocal distance, not infinity, for most landscape work — it extends the near limit of acceptable sharpness much closer to the camera while keeping infinity just as sharp as focusing directly on it would. At 24mm f/8 on full frame, focusing at infinity wastes everything closer than roughly 2.52 meters; focusing at the hyperfocal distance instead brings that sharp range down to about 1.26 meters, with infinity still fully sharp.
Why Infinity Focus Is Rarely the Right Default
Focusing exactly at infinity is the far edge case of depth of field, not the point that maximizes it — everything nearer than the hyperfocal distance's near limit falls outside the sharp range when focused at infinity, an entirely avoidable loss for a composition with any foreground element. The only situation where infinity focus is actually correct is when nothing in the frame sits closer than the hyperfocal distance anyway, at which point both approaches produce an identical result.
Why This Isn't Always the Right Call Either
Hyperfocal focusing maximizes total depth of field, but that's not automatically what a given shot needs. If your nearest important subject sits closer than the hyperfocal near limit, focusing at the hyperfocal distance still won't render it sharp — you'd need a narrower aperture, a wider focal length, or a deliberate closer focus point (accepting that infinity is no longer perfectly sharp, which often doesn't matter if there's nothing critical at true infinity in the frame).

Frequently Asked Questions
Does infinity focus on my lens's distance scale actually mean true optical infinity?
Not always precisely — many modern lenses' marked infinity position has a small margin built in for temperature-related focus shift, and on some lenses it can be slightly imprecise, which is a separate reason many photographers prefer focusing on a real distant object over trusting the infinity mark exactly.
Is there ever a real reason to deliberately focus past the hyperfocal distance?
Rarely for photography, since it only reduces near-side sharpness without extending far-side sharpness beyond infinity, which is already the ceiling — the one common exception is when a photographer wants a deliberately soft foreground for a specific stylistic effect rather than maximum sharpness.
