Use or don’t use auto ISO

Coming from the film world I had a conceptual problem with ISO/ASA in that those setting were governed by the film you were using. There was fast film and slow film, loaded for different situations. There was push processing but only for special situations. In theory the ISO/ASA number should be designated by the SD or CF you are using. I,know all is different now but I still have this nagging history - I'm old but adjusting.
Not determined by the memory card but by the sensor. Each sensor only has 1 ISO value.

leave the auto ISO off and only increase the ISO from the lowest posable setting when required.

I tried to get the bird to pause before flying from open sky to down below the tree line while changing ISO.

Actually I am the one that needs training! :sm09
Auto ISO has been good to me with the wildlife scenario. Another tool...

For birds and other wildlife, I use manual mode with auto ISO 99% of the time, set with a ceiling of 3200, which I have over-ridden to 6400 or 12,500 on (rare) occasion. Picked up this method along with back-button focus and other slick tricks from Steve Perry at http://www.backcountrygallery.com Steve's website is the absolute best I've found for nature and wildlife photography, especially for Nikon! ( I own a Nikon D500)..

I set everything. If I wanted the camera to make the decisions I would have bought a cheap point and shoot.

I have generally kept auto ISO on and just over ridden it when called for. I am now wondering, however, if I should simply leave it off. To that end, I’m curious what others do.
I have needed Auto ISO on two occasions. One was a CONFIRMATION service at a Catholic church. Each young person that came up before the Bishop was photographed as the Bishop put oil on the forehead. A shot was taken every 20-30 seconds. There is no way I could have adjusted ISO that quickly. Can you imagine taking exposure readings every 20-30 seconds and adjusting?
The other time was at a AA PRO baseball game. I shot at aperture of f/2.8 and shutter speed of 1/1000s or 1/1250s. Auto ISO really is nice as the sun is setting. For sports, I probably will always use Auto ISO. It's great. Just one thing I don't have to worry about.

Dave, it seems to me that BIF would be the perfect time to use Auto ISO. Birds often come from the shadows into full sunlight in a matter of a few seconds. Do you really have time to adjust ISO?
Now if you are shooting those Earth shattering blue jays at the bird feeder, you might have time to adjust the ISO. Otherwise, I think Auto ISO would help to get more keepers.
