Kinda hard to do, since I have the *istD.
I was wondering if there was some (over) exposure level that related to the
turn on of the blinkie - like 1/2 EV or some such measurement.

Which raises an interesting question....
@ what level of over exposure are the blinkies turned on?
Easy enough to find out. Set your camera to JPEG, make a few exposures
and force the blinkies to fire on known regions in the image. Download to
Photoshop, then measure the RGB values where the blinkies were firing.
If you save the image in RAW format, extract the JPEG preview and measure
that, then compare to what you can extract as detail with a RAW
converter. That will tell you how much more latitude for overexposure the
RAW format nets, and lets you gauge how to interpret them very precisely.
I did these tests about 10 months ago... If I can find my notes and the
images I used as test, i'll post them.
