merv said:I have used the auto ISO on my D3s to great effect. However, I have been told that the D300's auto ISO is rubbish and have never used it. Has anybody any comments please?:bang:

I think you've been told a fib. It's the same system and works just great. Why not just try it?
I think they have been meaning that the high ISO performance of the d300 isn't great.
