The problem with auto-ISO...

The problem with auto-ISO is the same as the problem with A or S -- you are relying on the camera's metering for adjusting exposure.  The folks who use M (including me) are using M because we know the camera's metering can and will be fooled, and will make mistakes, and we (the photographer) know *better*.

There are exceptions, of course.

When shooting sports with clouds coming and going, with players entering and exiting shadows, I am more inclined to use the camera's metering (including auto-ISO).

For indoor events, where lights and reflections and people's attire (dark suit vs. white gown) will sway the camera's metering, we get better results by fixing the exposure for (in most cases) people's faces.

That's it, in a nutshell.  That is everything I know...  and more.
