Forget Auto-ISO und the other auto-functions. Dial in the wanted ISO, the wanted aperture and the wanted shutter speed.

That gives the best results.

I disagree. When I take pictures of my son indoors, I set my camera to Av, limit my shutterspeed to never go below 1/1000s and set auto iso to 100-3200. If he gets some bright lights on him I get cleaner images, and I get properly exposed images when he is hit by a shadow, and always freezing his motion. Any other mode and I would either get too long speed, to much or little dof or blown images in bright light in manual mode if iso 100 on 1/1000s is too bright.

Exactly.  Try setting ISO manually in sporting events where clouds are racing by at high speeds with bright sun popping in and out.  This is where ISO safety shift ON, Av = f/6.3, Min shutter speed = 1/500, ISO = auto comes in very handy.  If you do it the other way, you lose your job because 1.  you miss too many shots fiddling with the ISO setting during fast action and 2. your photos aren't exposed correctly.

Disagree:  There are so many dynamic/ fluid situations where manual settings would mean lost opportunity.

Canon recommends a camera reset after installing new firmware.  There are many combinations of options that can make weird things happen with a major firmware upgrade.
I'd do a camera reset and then restore the settings one at a time if you want to avoid weird happenings.  If you did that already, and its happening, then let us know.

That's good to know, as I've never done that before!

Thanks,

You probably had safety shift enabled too.  Set you high limit for auto iso and also disable safety shift and test.

"it does not state this in the "new" firmware manual Canon released"


Can anyone provide the link to this new firmware manual? I may have missed it along the way. Thank you everyone. Looking on Canon's website, the latest 7D manual is dated June and I don't see a updated version.
Thanks again.

You didn't miss anything, except perhaps clicking the download link and opening the file.  The manual dated June, 2012, has a notation on the front that the manual is for a 7D with firmware version 2.0.0 or later.

Regarding the Max ISO setting. As I understand how this is generally implemented in Canon cameras, its not a hard and fast limit. The camera will try to abide by your settings...but if it is unable to achieve a proper exposure by following your configured settings, I believe the camera will still do what it has to do to get any exposure at all. In other words, it opts to photograph something, rather than nothing, even if its not exposed exactly how you would prefer.
