Will your "Focus" (pun-alert!) be on real estate listing photos:  The best angles for certain rooms, decluttering, not-tiliting, etc..... or will you be getting into some of the actual basic concepts of photography such as shutter speed, aperture and depth of field? 

If the latter, a camera with a manual mode would be necessary so students could experiment with their own exposure settings.

In either case, as others have mentioned, a wide angle lens is a must for real estate work.

If you will be getting into photography basics, one of the best things about digital is being able to use software that will display your EXIF data.  Reviewing the exposure settings for your best shots, helps you come up with ideas of what settings to use in future shots.   Here's a sample from Breeze Browser.

That said, if the Focus of the course is just simply to take better photos of listings, and the students aren't budding photographers, you could do worse that reccomending the Kodak V705 that Jeff Turner wrote about back in November.

The image quality has been fine for me.  It has become my always-in-my-purse, carry-everywhere camera.  One thing, though, that little camera may feel too small for some people.

I suppose one could pattern the class around photoing an actual house:

1.  Stop the car, get out, LOOK around:  Where are the trash cans?  Are there cars in the driveway?  Photo the exterior from several angles.  Start at one corner, walk along the front, stopping to snap every few feet.  Walk across the street, walk down the block.  What do you SEE?  Walk along the sides of the house, the rear, what do you SEE?    Keep snapping.

2.  Go inside, LOOK for angles.  SEE where the light is.  How does backlight from a window affect your shot?  How to compensate for backlight.  What do you SEE holding the camera a little higher?  A little lower?  What objects do you SEE?  Should you center the object, or photo it off-center?  WATCH out for mirrors.  Shoot from each wall and each corner of a room.  Shoot cross-angles.  Shoot through doorways.

A lot of photography revolves becoming aware of what your camera SEES.

Maybe one of the agents attending the class could make one of their listings available, and the whole class could take a field trip  to that property.  The sellers of that property would probably be thrilled to have a whole class full of agents touring and photoing their home!

P.S.  I could also see the class having two separate sessions:

Session 1 would be the field trip to a property.

Session 2 would be in a classroom setting and would focus on the "digital desktop darkroom".... How to use imaging software to correct contrast/exposure, crop, de-tilt, and re-size photos....

Oh, No, Mike, shooting a lot of photos to get a few good ones is a very good receipe.  And digital frees the photographer from the 36-shots-per-roll limitation of 35mm film.   Maybe another topic for Lee's class could be about changing that mindset.

Most pros shot a lot of photos to get one keeper.  You can verify that by reading photgraphy forums and message boards around the  'net.  And think about how a fashion photog works:  The model is moving about, striking different poses, the photog is snapping away, adjusting lighting, snapping some more.  Only one of those shots makes the cover.

And here's a very good reason for agents to shoot their own photos that has nothing to marketing, and everything to do with legal risk management:  Sometimes as you review a bunch of photos to choose the best, you'll notice evidence of a condition that needs to be disclosed --- as in  "Hmmm, I didn't see that water stain under the window before ... have to ask about that".... 

If you had hired a pro, you might never have noticed the water stain.... that came from hillside runoff....  that turned out to indicate a geological issue ..... and disclosing it kept the agent out of court....
