Well since you are a "tinker" type
I suggest you go out and take some pictures
with a really good lens of a really high contrast
scene using a DLSR and a wide range film and SLR and
find out for yourself. If you do not have access
to really good film printing, just inspect the 
negatives....

I have never read
anywhere that digital can yet match the dynamic
range of the widest range films. And this is all
color of course, if you go BW and pull processing
the range of film would be even greater....

Well, John, it's time for another aspirin .... too many graphs and
charts and logs of this and that.  However, one paragraph stood out
amongst all the techo talk:

        "Before I go any further I should point out that 
        this test is only going to produce a theoretical 
        result.  Since I am testing film, the dynamic range
         that I will be calculating will be much higher than 
        any figure normally quoted for film because very 
        small changes will be detected. At some point 
        these changes will become irrelevant to the 
        appearance of the image but since this is a subjective 
        judgement I'm going to leave it at the calculated value 
        for now.  I'll return to the subjective arguments later."
