I have the 580EX, but there's no place to plug anything into it. The
only connection for an external device is for the hot shoe, and the
photos they show for the ring light don't help. Nor do their pdf
operating instructions, which have no illustrations at all. I
gather it's a flash as a continuous light source should use TTL just
fine.
I have a Coolpix 4500, which was my first digital camera and one I no
longer use, and the Nikon Cool-Light SL-1, which threads on the front
of the lens. It's a continuous light source with eight leds in a
ring structure. I used it only once or twice but it seems to work OK
at distances less than about 12 cm. It's clearly for macro use
only. Here's a review of it: http://www.cs.mtu.edu/~shene/DigiCam/

Walgreens is selliing little (about 8 cm long by 1.5 cm

for $5. Would a half-dozen of these clipped to a ring around
the lens work as a serviceable ring light? No ancillary power
supply would be needed. Of course, you would have no control of
the intensity except by varying the number of lights. I have an
led flash light that has tremendous intensity and range. It's
too big for this application, but the batteries (three AAAs)
have lasted for 1 1/2 years.
Another question. Could one photograph a white card illuminated
by led flashlights and get a rough idea of the spectrum by using
the computer's built in color analyzer? Photoshop will do the
same thing.

Guess I'll have to go to Walgreen's.......
My 4 LED flashlight powered by 3 AA cells finally started getting
less bright so I replaced the AAs....... Been about 2 - 2 1/2
years 0n the originals. The LEDs sure don't like power!
