I picked this up for my wife who lives in "Auto" mode most of the time. I gave her an SB400 to use at family gatherings and for some reason the D3200 keeps choosing ISO 2000-3200 even with the flash attached. I've never had this issue with my old D50 or D300 where it generally lives at ISO400 if you let the camera do the thinking.
I even tried with the pop-up flash and it chose ISO 2200 for the shot with flash firing. Is there a new setting I'm missing somewhere?
With the newer Nikon's the way Auto ISO is used with flash has changed. It tries to balance the background ambient exposure more with the foreground and raises ISO quickly to do that. The change came after the D90 and implemented with D300...I think. The new models set Auto ISO according the metering of the ambient light, before the flash, regardless of if the flash is present or not. This means indoors (dim light where we need flash), the TTL flash always discovers it is working into high ISO. This is sort of a forced balanced fill flash situation, regardless how dim the room. Some like the new implementation and some do not. The way to use flash with a lower ISO is to switch out of Auto-ISO or to a exposure mode that allows you to set the ISO to the value you want.
