Thanks very much for the information about depth of field, it was most
helpful.

Is this something measured or taken out of tables?  Where is the lens
focused?  At infinity?  (You cannot
quote a DOF range without indicating where the lens is
focused unless if you are talking about the Hyperfocal
Distance. If infinity is the outer range of the DOF
then most probably you are talking about the Hyperfocal
Distance, which is the twice the shorter DOF limit and
that's where the lens if focused.)"

I was simply reading it off the DOF scales of the respective cameras.  And
you hit the nail on the head, I was setting the outer range of DOF at
infinity and reading the camera's inner ranges for comparison purposes.

I had considered this, but was too lazy to try it out when I could just ask
the "old hands."  :)  Might still run a trial, though, next summer when
there's plenty of free time for me.  After all, my tolerance for fuzziness
might subjectively be more or less than that of the camera manufacturers.

Thanks again!
