[OM] Re: Focus problem

[Chuck Norcutt]

Neat tool but probably overkill for the task at hand.  Even at 100mm f/8 
and assuming 35mm frame size and CoC the hyperfocal distance is only 
about 125 feet.  Using an E-thing at the equivalent focal length of 50mm 
and appropriate Coc the hyperfocal distance is only half of that or 62.5 
feet.  Fairly easy to guesstimate or even pace it off.
