Why are you using Auto ISO with flash in the first place? Never, never us Auto ISO with flash.

Rubbish. I use it all the time with my D90 and with the D200.

Bodies D90 and prior boosted flash power before boosting ISO. This allows you to use the auto ISO as an underexposure "safety net".

D300S and newer boost ISO before boosting flash power.

The work around I'm told for newer models is to set the flash to commander mode. In commander mode the newer cameras are suppose to revert back to the old behaviour and boost flash power before ISO. However my most recent camera is the D90 and I have no way to verify this. Would be very interested to know if this is the case, so if it works please post your experience.

My forum postings reflect my own opinions and not those of my employer. I'm not employed in the photo business.

I can confirm that built in flash goes to "legacy" mode when in commander mode. SB400 does not support commander mode so no sigar here. Bummer.

Will test SB900 later.

Thanks for suggestion
