Most people I have introduced to Merklinger's work have the same reaction as
Chuck and Iwert. BUT my experience is that the DoF markings on modern
lenses are hopelessly optimistic - I suspect it is because modern lenses and
film can vastly outperform those of the 1930s, when the definitions
underlying DoF tables were "agreed".
If you do make it through to his example images, you might be in for a
surprise.
I originally came to his DoF paper having found his work on focusing view
cameras - and by extension, tilt lenses. For that application, I found that
his explanations were absolutely spot-on.

Subject: [OM] Is the emperor called hyperfocal distance that well dressed?
Interesting argument that if one desires infinity to be in? sharp focus
focus at infinity with little loss. Hyperfocal distance has its drawbacks.??
Probably depends on what the emphasis of the image is.?
Only read? the paper in a cursory fashion and we'll see what Dr. Focus et al
have to say.
