I did a similar experiment. The result was that there are only small differences visible. However, they are there! The difference between -1 and -2 is just visible to the eye. Take a look:

Here are 7 small pics taken with the ist-D and 500 FTZ: http://www.donsauction.com/pdml/flashtest/FlashTest.htm The chair is light/medium brown. They are 1 stop of EC apart from -3 to +3. No difference appears until you reach the plus side, +1, +2 and +3 show an increase in exposure. The -3, -2, -1 and 0 are all the same. These are at 1/150th, Manual mode, ISO 400 with a Vivitar 70-150/3.8 set at 150mm/f8.0 at 20ft. Any ideas on why +EC makes a difference and -EC doesn't??
