Yes, Search is often disappointing, but the titles can be disappointing, too. "Something Different," "Help," "Advice, Please." If the title doesn't state the topic, the Search feature isn't going to find it.

Using auto ISO DOES give you the lowest ISO possible; based on the required and desired shutter speed and aperture.......!

I use a D750 for action shots and set the auto ISO maximum to 3200 and minimum shutter speed based on lens chosen. If noise is ok I use capture one but if noise is more obvious I use DxO to process RAW images.

Great information, great question, thanks!

Isn't that the function of Auto ISA - to use the lowest ISO for correct exposure given your aperture, shutter speed and compensation.
That's how it works on all my Canons

Nope. This is not a certainty.

I can only speak on my behalf and I NEVER use Auto WB. I prefer to use a setting to approximate the lighting present on my subject and an example is Sunlight setting when the sun is shining.
For birds in flight I use a shutter speed that allows me to freeze action and that shutter speed has to be higher than the focal length of the lens I am using. If am using my 80-400 VR lens I know I need 1/500sec minimum shutter speed although 1/1000sec would be much better. At times I slow the shutter speed only for panning.

You can select a range limit of ISO on my cameras. So you don't go to high but can get the shot.
The new digital camera's are amazing with their ISO options. Test you camera and find out what happens
with different settings as far as noise. A lot for camera claims are not always what they claim.
I am watching and older series The Killing (started in 2011) on Netflix.
I was taken back about how much noise some of the low light footage has. It would never pass the test today.

Excuse me, this is thread about auto ISO, not auto white balance.

I use Manual + AutoISO 90% of the time for everything. I stumbled on the technique quite by accident. Reading John Gerlach and Steve Perry's posts helped me understand what I had discovered. Before I started using AutoISO, I would press the shutter and get that dull, no-click feeling of pressing a dead button because the camera did not shoot. I first noticed this phenomena shooting sports on poorly lit football fields. When the action moved to sidelines or end zones, the camera would not engage. AutoISO fixed that. Do I sometimes have a noisy image, yes... but if I miss a TD or great catch, it's on me and not the camera.

My question to those who don't advocate AutoISO is this: Given there are only 3 legs to the Exposure Triangle and you have locked in aperture and shutter speed, do you simply accept not getting the shot or having the camera not fire when light conditions change at a precise moment that would dictate a higher ISO? Or do you go with Aperture priority and accept blurry photos because SS dropped dramatically? How do you overcome? It would seem to me that quickly changing the ISO yourself is simply losing reaction time the camera is built to do for you.

you are right on....but also you can set the limits (min/max) ISO in camera to keep it in acceptable range

RRS Loc: Not sure

I too have been shooting a long time too but back in 1970 was there such a thing as auto ISO. Do you know when that was first available on our digital cameras?

I agree! My Canon 5dIII is super on manual with auto ISO, especially with BIF. If I tried toget all three settings for each shot I would spend more time playing with dials and missing what I was there for. As anotherview says, it all about your camera and sensor etc. I wold also suggest if you want tact sharp. to practice spot focus, AI-servo and continuous fire. Shoot burst of 3-5 and you will increase your odds of nailing the bird.

Auto ISO is equivalent to the plague. Run away!!! Run away!!!
