The chart on the underside of the lid on my older Realist says
that at f/16 the DOF is 4' to Infinity.

I think on the camera focusing scales, the distance between
40' and infinity is pretty small while the difference betwee
3' and 4' is pretty big, so exactly where one sets things
(plus the circle of confusion def'n) can make quite a difference.

And the Realist Cover?  Not much different than the Revere!
