Re: Zone Focus & hyperfocal marks

[Andre Langevin]

By the way, all Pentax WA lenses has a zone focus mark (a red number 
on the distance scale) to be aligned with the f8 mark (red also). 
You are then in hyperfocal mode as Doug explained.

It has been mentionned here that Pentax might not be conservative 
enough on their hyperfocal scales; to "drop" one stop is safer, i.e. 
to use the 5.6 marks at f8.
