Thanks. I can't remember if noise reduction was on or off. Probably on... are you indicating that possibly because of the type of shot (night shots) that there is more work to do with noise reduction than a typical daylight shot?... because I haven't changed any modes, noise reduction or file format.
Noise reduction only kicks in on "long" exposures (I'm not sure offhand what this is, the manual may say, but I doubt it :)
As another note, every time I've had my *istD do something odd, like not fire the shutter or something really weird like only fire once I release the button and then not properly, its been due to flat batteries. Sometimes the batteries have been fine until I swap lenses too, either the drain is significantly different, or its something physical... it doesn't happen a lot, but fresh batteries always fix it. Half the time, re-inserting the same batteries will fix it....
Its battery indicator is not one of its strong points...
