I have owned a few conpact digital cameras and I have been left with
the impression that the infinity focus setting is nothing of the sort
and is more like 30 feet. Has a study been done about this that I
could link to?


Depending upon the lens's actual focal length, 30 feet might be at or
beyond infinity for that lens.

Too infinity and beyond!!!

It would not be dependent on the lens's focal length, but maybe beyond
its focusing capability. BTW I know of no way 30 feet can ever be beyond
infinity. :-)

Actually everything you intended does make sense and I think most
everyone would read it in the way you intended. Which is a good thing for
me, considering how often I make like errors.
