Hi Jan,

Ahh, found it:
Quick and easy reference:? see first two tables:
http://www.cambridgeincolour.com/tutorials/depth-of-field.htm



To derive things from first principles see Merklinger:
http://www.trenholm.org/hmmerk/TIAOOFe.pdf

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?
