On their WA lenses (since the Super-Takumar lenses), Pentax have a number on the distance scale that is red, as is also the "8" on the aperture ring. If you align the two red numbers, you are set at hyperfocal distance for f8. Check where is the infinity mark and you'll understand.
Hyper focal distance nothing to do with zone focusing. (William Robb)
Well, hyper-focal focusing is one way of doing zone-focussing, no?
