Hi Jan,
Ahh, found it:
Quick and easy reference:? see first two tables:

To derive things from first principles see Merklinger:

Near and far limits of dof:
?
D1 = (f2D + gfD - gf2)/
1 = (f2D + gfD - gf2)/
????????? f2 - gf + gD
D2 = (f2D - gfD + gf2)/
2 - gf + gD
D2 = (f2D - gfD + gf2)/
2 = (f2D - gfD + gf2)/
?????????f2 + gf - gD

(I would plot it out the proportion rear/front of the focal distance for you as
a f(FL) if? I weren't stuck at work till 9PM)
2 + gf - gD

Interesting. I may have to go revisit the textbook I've been teaching?
from for some decades.
Have any references for that?
