Subject: ist-D overexposure


I've noticed that my ist-D overexposes many of my pictures when using the 
af-360 flash. Took me a while, but finally I've realized that its not 
random. It will always overexpose (by more than a stop,) when using my 
Tokina 28-70 2.8, when the zoom is between 30-40. Here some test pictures 
(about 150k per picture)

@28mm www.xdstech.com/istd/test_28mm.jpg - fine
@33mm www.xdstech.com/istd/test_33mm.jpg - overexposed
@35mm www.xdstech.com/istd/test_35mm.jpg - overexposed
@40mm www.xdstech.com/istd/test_40mm.jpg - overexposed
@45mm www.xdstech.com/istd/test_45mm.jpg - fine
Why would the camera do this?
Thanks
