Customer Question

I have a Nikon D300 using auto ISO, min sensitivity 200, max sensitivity 3200, min shutter speed 1/500, centre weighted exposure, aperture priority. Camera works beautifully without flash, but with flash the ISO reverts to the minimum (eg 200) irrespective of lighting conditions. No good for fill flash with birdlife. Is this normal please?

Hi, thank you for contacting My name is Russell. I will do what I can to provide the right answer to your question.

It is possible that your camera has a problem, e.g. with either the flash control circuits, or the light-sensitivity sensing, or other things.

But to make quite sure it isn't an obscure interaction with an obscure setting(s) (combination, perhaps), you should do a Factory Settings Reset, and try it once again... then if it's the same, you definitely would need to choose between repairing it and replacing it, or just putting up with the flash deficiency doubtfully, or even using an auxiliary flash if possible and if you would prefer it.

Is the camera less than a year old?
