Another thing to consider is that most lenses designed for auto-focus, focus beyond infinity.
Focusing using hyperfocal distance, or focusing at infinity is best done with a manual lens.
Check out the DOFmaster link that Surapon provided and you might want to read this:
Thanks. I read both. I am not clear but infinity focus and Hyperfocal distance seem to be two different things. Using the link and the calculator:
Full Frame sensor
F8, Focal length: 40mm
Focus distance: 500m
It calculates to 6.17m as nearest acceptable sharpness and infinity as the farthest.
The focus distance is probably hard to estimate for a landscape shot. So am I not focussing at roughly 6.17 m to get this large DOF or am I focussing at 500m to get that? And what if my focus distance of 500m is totally off?
