Subject: Re: [Leica] depth of field scales and infinity

What you have described is called the hyperfocal distance.  On my lenses the place 
where the lines of the infinity mark cross actually mark the point of infinity focus.  
This technique will increase depth of field in front of the subject without sacrificing 
sharp focus beyond.
