What is hyperfocal Distance? This is certainly NOT an easy concept to grab! It is the distance between camera lens and the closest subject that is in focus whilst focussed on infinity.
Should one decide to focus closer, you will experience an unexpected soft effect in the infinity area. Opposite also true, should you decide to focus further, the closer point will also be of no good.
The best option is to do this manually. Focus on the most distant object, then manually change focal distance to as close as possible while still keeping an acceptably sharp background.
Also try to set the focus to one-third distance into the scene at very small f-stop. However to obtain maximum depth of Field, hyperfocal distance should be calculated.
Normal to shorter lenses are great to use this technique such as 50mm or 35mm
With longer lenses, hyperfocal distances are not great (very distant) so these are normally not used for Landscape photography. In Landscape photography you require subjects close also to be sharp which cannot be achieved with longer lenses.
