There are many discussions about DOF some with much math involved, why not set and lock the Aperture and Focus, then press the preview button and look around? See what's in focus and what isn't.
One other thing, if we ever loose the name Ugly Hedgehog I would suggest Circle Of Confusion as a replacement.
I never use the math- I use the depth of field preview button, if I need to check it at all.
Some people like to take things to the extreme here and it does get interesting at times.
Good alternative name, btw

I just keep general rules in mind and they mostly work - wide open (f2.8+/-) object in focus, if I'm far enough away, whats in front also. F8- in focus front to back. Closed down, f22+/- - object and what's behind it in focus.

Many cameras have a DOF preview button for this reason.

Check out Photog11's post on MWACs thread {middle of Pg 9}. Then go back to Pg 1 {please ignore the Trolls} and review the other examples and discussions regarding DOF. Hopefully your circle of confusion will be reduced ? ;-)

Also - I have found the Preview button gives a darkened view in which it is difficult to fully appreciate Bokeh.
Bokeh and depth of field are two different things. Bokeh has to do with the quality of the out of focus areas, particularly the highlights. Depth of field is how deep the acceptable area of focus is.

Yep - - understand that and did say what I meant. I cannot fully appreciate the out of focus areas when pressing the preview button because of the darkened view provided.
But - Goofy - - as a Pro - how often do you really use the preview button as compared to knowing what you're gonna get for any particular lens setting ?
Hardly ever and I don't have time to look up any chart. When I shot 4x5, I could check dof but that was under a hood.
