Re: [OM] IMG: Sunrise, Moonset

You seem awfully stubborn on this point that hyperfocal is a digtial 
concept. Here's a quote... and note the date
------------------------------------------------------------------------
When the lens is focused on the hyperfocal distance, the depth of field 
extends from half the hyperfocal distance to infinity.
Photography, Phil Davis, 1972.
------------------------------------------------------------------------

The concept goes back way farther than 1972.  That's just the earliest 
record I could find easily.  Apparently Maitani was a true visionary. 
He marked your OM primes with DOF marks to include hyperfocal (if you 
know how to use them).  He was a visionary since he must have predicted 
that digital photography would come along and then this strange digital 
focusing concept he'd created would be useful.
Once you understand what hyperfocal is all about, if you find that using 
standard tables and assumptions doesn't produce suitably sharp work for 
you then tighten up the specs to suit yourself.
