I use it in situations where I am unfamiliar with the lighting conditions and where I may not have a second opportunity to recompose and reshoot. I rarely use it with flash.

I use it shooting basketball games in gymnasiums. I set the aperture and shutter speed where I want them and let the ISO go where it wants to.

Never with strobe, almost always shooting wildlife because of the constant changing light. Remember, you can set the parameters of shutter speed and ISO in the auto ISO menu.

I never use it for long exposure and seldom use it with flash. I almost always use it for wildlife when the lighting can change from bright to shaded in an instant. With fast action wildlife in daylight I usually make the shutter speed top priority at 1/1250 sec until the auto iso reaches my maximum setting of 2000 before my shutter speed will start to drop below 1/1250.

Shooting wildlife, especially with a telephoto - I want to be able to manually control the shutter speed to make sure it is fast enough to use the telephoto hand-held, and I set the aperture depending on what kind of depth of field I want. Then with ISO set on auto I don't have to worry about the exposure. This is especially useful in the late afternoon and evening, when the ISO may get up to 10,000 or so - the Canon 6D handles that without major problems.

Same here but I use a Nikon D500

I use it often, usually A (aperture) or M (manual) mode on my Nikon gear. I find it underexposes shooting into a bright sky when I am in M mode, even though I have the parameters set correctly. Otherwise it's fantastic.

Quite frequently with wildlife. Got to handle that lower light earlier morning and later afternoon without sacrificing shutter speed.

I use it when lighting conditions are changing and I want specific Aperture and Shutter Speed settings.

It works well when the light is variable.

Hence not for sports in a gym. Not for long exposures. Not with a flash. But for everything else, put the camera in Manual Exposure mode an enable AutoISO.

I use it because I don't spend much time shooting in one direction, or one subject (hate tripods). I am often driving around the countryside, jumping out for photo ops, so lighting might change quickly.

I like to keep shutter speed at a certain minimum to help with camera movement due to my own motion, and I will change aperture based on how much depth of field I want. Auto ISO is fast, efficient and always works out except when I need to employ exposure compensation due to tricky lighting.

Just like a "walk around" lens that is more likely to be ready for anything, AutoISO is a walk around camera configuration.

Not worth much for those who enjoy taking half an hour to set up a shot. Terrific for those making split second decisions on where to point the camera.

How correct you are .., good answers on both replays ...

Thanks for this question and all these answers, this has been a help to me reading them. I just upgraded to a Canon 7D Mark II from a Canon Rebel T6 and am having to watch alot of online videos.
