    D200 is limited to a min 1/250th shutter speed in autoiso. D300 was
    too initially. 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.

    Which was my point. That when you can set exactly the correct aperture
    and shutter speed for the shot, your exposure is corrected through auto
    ISO. If the range of the variables is narrowed, the usefulness of
    auto-ISO decreases.

    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.

    I have been shooting with W/A DX lenses in FF, and cropping in PS.
    No decent results, yet.

    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.

    And many new cameras allow you to set the max ISO used by auto ISO, so you
    can simply choose at what point you think noise is excessive for the camera
    being used, and not go there.

    Good for you, I can't even use my EF-S WA lens on my FF Canons!

    Shooting in Dx mode isn't going to help much then either!

    There was nothing technically wrong with the images. Simply dull and
    uninteresting images.
