Dive in. It’s painless! What is the worst thing that can happen? Disagreement? An insult from some cruel fool?
While the Internet requires a thick skin, the vast majority of us just want to help. Ask away.

Most of the example photos in the link from the indoor concert have shutter speeds of 1/500 or faster. The answer may be obvious but why wouldn't slowing the shutter speed help? Wouldn't that be a reasonable way to shoot at lower ISO? even handheld?
The focal length comes into play too. I’m guessing when zooming in on individual performers it’s fairly long. I’d rather deal with noise than blur.

Perhaps because Canon has a 4,000,000 ISO camera with very good and usable images.
If you need to go that high get the right tool that actually produces excellent photos at 4,000,000 ISO.

If you have $20,000 to spend on a 2.26 megapixel camera.

As far as the ISO numbers are concerned, they are ... (show quote)
It’s a factor af two because that’s what each full stop is, whether it’s aperture, shutter speed or ISO.

What all this comes down to is that while they talk about sensors being ISO invariant, they really aren’t there yet. They get better and better but a truly invariant sensor is still a unicorn.

Gets like this a lot.

Do you want to shoot at 4.5 M ISO?

As you raise your ISO, you see more noise. You should almost never go over, at the most, 800. I set my Sony’s to ISO Auto and then shoot in Manuel mode. I use minimum 100 iso and maximum 6400 and then adjust if I need to

800 is almost my normal walking around ISO for my D4s. Did you mean try not to go above 8000? That I can agree on.

I meant try not to go over 800 but I get good images at higher iso that I adjust in post
