My old D70 goes about Auto ISO in a very different way when combined with "P", "A", or "DVP" modes. -- Regards, Savageduck |

I know I left requests to allow shorter on the Nikon Tech Support forum and in the 1.1 firmware release this was changed to allow much faster speeds to be set. |

I know I left requests to allow shorter on the Nikon Tech Support forum and in the 1.1 firmware release this was changed to allow much faster speeds to be set. There is also a practical limit in noise level at a higher ISO. My D200 ws quite noisy above 800. My D300 produced usable images at 1600-2000, although there was some noise. Though with today's noise reduction software, my guess is that the limits may be higher. -- PeterN |

If the range of the variables is narrowed, the usefulness of auto-ISO decreases. Who said one need specify an exact shutter speed? Maybe there are other requirements. Shoot long focal length (fl 560mm or 800mm on a D300), even with image stabilization, one wishes to pu a lower limit on the shutter speed. Especially in an environment when the lighting changes quite drastically and one can not manually adjust. Or action shots fast enough to freeze or at a minimum partially freeze motion and again when lighting may change quickly. |

One use for auto ISO, is shooting sports, where the maker wants freeze action shots, with specified DOF. As I write this I am thinking that any time the maker wants control over both DOF and shutter speed,, auto ISO is the enabling factor. -- PeterN |
