Does this mean you are displeased with us? May we have another chance
to rise above our limitations? Please, sir, we live only for your
approval--we ask no reward beyond your validation of our worthiness.
Pray pose another conundrum, that we might bask in the golden light of
your approbation, God willing.

Its an interesting approach, worthy of some experimentation.

Thanks for the posting.

Or anyone with a pulse and is an action-shooter in changing light.

Writing off auto-ISO sounds like a cool thing for people who like to beat
their chests, but it is really an utterance of ignorance.

When you have manually chosen the aperture and shutter speed you want,
there is no better ISO to use than the *HIGHEST* one that doesn't cause
blown highlights, on 99% of cameras (and probably 100% of DSLRs). To have
this automated would be a good thing. Even better would be the ability to
create user-defined auto-ISO/exposure modes where a combination of f-stop,
shutter speed, and ISO is chosen by the user in a user-supplied chart for
every metered EV value.

In a perfect world, ISO wouldn't even exist, except as an "exposure index";
IOW, it would only tell the camera what brightness to show the review image
at, or what sensitivity to be assumed in the JPEG; the RAW data would just
be a count of photons, and the average number of photons in the image would
simply depend on the compromise the user makes in their Av and Tv choices
vs absolute exposure.

Real cameras are not currently like that, though, and have anywhere from
slightly less to greatly less read noise, relative to absolute signal, at
the higher ISOs. Auto-ISO in manual exposure mode would be a nice thing to
have, provided it tried to use the highest ISO possible without clipping
highlights. The EC control could turn into a logarithmic "highlight
escape" control in this auto-ISO mode.

I can't tell if you're serious or sarcastic here, but the most industrious
people, pro or serious hobbyist, utilize resources available to them when
they are best fit for the job. Many pros are fairly ignorant of the
possibilities of their equipment; they just do what seems to work and look
no further. Serious hobbyists are usually the ones to figure out how
things really work, because they have the time to do so than many people
who have chosen photography as a career and are busy with clients.

As ironic as it may seem, the most useful situation for auto ISO might be
with manual exposure. That is the situation in which photographers may be
fooling themselves in thinking that they can out-think automation, as long
as the camera provides a mechanism which allows the photographer to allow a
certain amount of the image to clip in the camera. Based on that guidline,
the camera can then use the highest ISO that doesn't exceed this clipping
percentage.

Interesting ideas John.

I tried auto-ISO but it was not useful. What I explored was shooting in
aperture priority with ISO kicking in when the shutter speed exceeds the
hand-holdable shutter speed but it was too much hassle to change the
trigger whenever changing prime lenses and completely hopeless with a zoom.

You really wish they'd let you program the behaviour of
auto-ISO to (also) depend on the current focal length ...

I would have though a stop of two would be worth the hassle at least some of
the time?

I manually adjust ISO as needed, keeping an eye on the shutter speed.
I'm sure there would be times with a prime lens that it could be useful
but the menu diving seemed not worth it. I have about 5 or 6 settings in
the D200 'recent settings' menu and maybe I could get used to adding
that one also but laziness overcame. You have to remember to turn it off
too so it doesn't mess you up next time you pick up the camera.

Depends on what your aims are. It might be useful for some, and not for
others.

And for those that would like a couple of stops of shutter speed for
nothing, I see no negatives setting auto ISO to auto from 100-400, is the
noise that bad at ISO 400 on the D300 not to?

I have no experence with the D300 but on my K10D it is pretty easy to
adjust, how hard is it on the D300, a stop or two would normally be worth it
but I will admit I normally use Av mode and just have ISO set to lowest
setting?

I have a D200,
(the D300 menu is a bit different from what I've seen, I believe you set
a favorite menu rather than recent settings).

menu button
down 2 to recent settings menu (from format menu)
scroll down thru four options:
1) off
2) on
3) max sensitivity
-200, 400, 800, 1600
4) min shutter speed
-15 speeds to choose from (3 screen-fulls)

Not that bad if you decided that's really what you want but I don't
think I'd make that decision until I had already shot a bunch & figured
out I needed it. My default without thinking is ISO 100 aperture priority.

Remember to turn it off when done.

When are you ever really done though? I could just leave it on & watch
the ISO in the viewfinder and adjust the aperture to keep ISO at 100
when desired. Oh, turn it off when I need ISO 100 with a shutter speed
faster than 1/250.
