Is the lens used in taking the picture (with a Canon 20D) identified
in the EXIF? If so, how can I view it. PS CS doesn't include this
info in the browser.

IrfanView viewer Image/Info (or just press "I"). At the bottom of the
dialog, select the Exif Info button.

The lens isn't directly identified, but if it's a zoom lens, the maximum and
minimum focal lengths of the lens are displayed in the EXIF data.

As below:

MaxFocalLength: 400 mm
MinFocalLength: 100 mm

Canon's file viewer utility (FVU) will display this.

In addition to focal length, aperture etc...
With my 10D you sometimes get some very odd distances at which the lens is
focused. If this same data is used in ETTL II flash calculation, I'd be
surprised if the exposure is anywhere near "correct".

The file Browser in my copy of PS CS has an entry in the EXIF for the 20D
for both focal length and lens. The lens entry may not be quite as specific
as you are looking for but, for example, if I am using my 24-70mm it says:
24-70. It does not say 24-70 f2.8L USM - if you are looking for something
that specific.

I just checked my PS CS browser again to see if there's any reference
to the lens as you indicated. I couldn't find any at all. Do you
have to turn on some function in PS or the 20D?

Yes - in the data display in the lower left corner of the File Browser make
sure that the Metadata tab is clicked; then click the small arrow to the
right of that and you will be able to choose data display options. In mine
the 'lens' entry was checked by default, perhaps that was not the default in
yours.

Found it! I unchecked the "hide empty fields" and the lens field is
visible now, but empty! Perhaps the 20D doesn't record this info?

Is it an older manual lens?

A bit off topic from the OP...

Does anyone know a utility that will easily create text files for the
exif info simply by right-clicking selected files in explorer?

BreezeBrowser does a nice job of this but it's still pretty tedious
firing up the program, browing to that folder, mucking through menus
etc. Other programs like Exifer are similarly complex at creating comma
delimited files. It'd be nice to have an editable config file to choose
the fields you want & maybe add formatting like html.

JHead is a command line utility that could be used to write a script
maybe to handle multiple files. I don't know what it'd take to run that
from a right-click menu but it'd be a very simple fast thing. I could do
that with PHP but it'd be a pain going to that screen. I tried jhead
with a batch file but a script is needed to handle multiple files.
