Depends on my situation if I use auto or set it. I do many pics that happen suddenly and don't have time to set up the camera so Auto ISO and P mode is where I keep my cameras unless have the time to set up for a situation.

Yes, to go totally manual means no auto ISO, but that wasn’t the question. If you paid any attention you would realize that people are talking about using auto ISO in rapidly changing conditions when you don’t have time to change settings every shot.

It works, but you can wind up with very high settings and lots of noise. Some cameras let you set how high the Auto setting can go. Still, getting a picture with noise is better than not getting any picture at all.

I use Auto ISO once in a while when I am doing city shooting, and I used it on my 60D, just set an upper limit

When set to auto, the ISO adjusts automatically as needed to produce a proper exposure.

The aperture in your text example seems high, but even so, the ISO set on auto would adjust for it.

You may wish to study the exposure triangle to learn its ins-and-outs.

Note that going to full manual requires you the photographer to make all three exposure settings for capturing a subject: shutter speed, aperture, and ISO.

Hence, if a given exposure in full manual falls short of your expectation, then you'll have to decide which setting(s) to change for a better exposure.

Good luck.

Surely not always zero editing? We may still require some Post in order to overcome the inherent aberrations associated with the sensor?

This would be the same for Canon as well.

It always never stops amazing me how many of the UHH members always have a sarcastic answer to a simple question that someone asks that’s trying to learn and I thought that this site was created for just that purpose, now mind you I would say
85 % of the members are great people but the 15% of you out there that have smart ass answers must have a cactus stuck up your butts, just my observation from reading the posts over the last few years.

I leave my Nikon on auto ISO almost all the time and it works fine; I use it in situations where I can't take the time to set ISO, shutter speed and aperture such as at sporting events, (fast moving) wildlife photography or low light conditions where I purposely want a long exposure time. As others noted it's important to set a maximum ISO and when I'm on either Aperture or Automatic mode, I also set a minimum shutter speed of 1/60th of a second to prevent blur from hand-holding the camera. So far, noise at ISO settings as high as 6400 (my maximum auto ISO) don't result in noticeable noise.

Yes, auto ISO is good as a starting point that you can then fine tune with exposure compensation, if needed.

Auto everything is, ceteris paribus, good, imho. When I go out to shoot, cameras are set auto ISO and program mode. This means that a very fast shot has the best chance of being usable. But that is the starting point, and from that one adjusts -- ISO, aperture, shutter speed -- to suit the needs of the particular situation. I think that it really is that simple.

If you have consistent predictable light and a planned subject, you don’t need Auto-ISO. If you’re into Manual mode and still taking snapshots with unpredictable lighting or subject, yeah, then Auto-ISO would help. Or maybe just AUTO mode.

Yes. I think it's a good idea to set an upper limit on ISO depending on how well your camera tolerates it without producing noise. But it's a good way to get instant exposure updates with fast changing conditions and with fast moving subjects flying in and out of shadows.

I agree.

Last year I experimented a little on a newspaper assignment, with the upper limit on my D500 set at 51,200. The results were to my eye surprisingly good and certainly usable:

This is true, but it can be a great tool in changing light. I use manual so I can choose the shutter speed and aperture and use auto ISO with a ceiling of 6400 on my Sony. The Nikon 500 can tolerate a higher ISO ceiling.

I like the advice given to test your camera to see how high of an ISO you are OK with.
