I take it normal camera viewfinders - the non-adjustable ones - do have
a slightly negative value as their standard setting.
Now, is there someone around here who can make any sense of all this?
Further info: I am far-sighted and my eyes have lost practically all of
their close-focussing ability over the last few years.
Viewfinders have an apparent viewing distance of about 1 meter. A -diopter
moves that apparent distance farther away, a + diopter moves it closer.
