I was just doing some reading about Auto ISO. What drawbacks, if any, are encountered by using this on a regular basis?

I shoot birds and animals with Auto ISO in manual. I haven't experienced one issue using this mode. If anything, it has helped me greatly with the changing light, especially birds in flight.

The only drawback that I find is personal. I don't like the camera making decisions for me.

The obvious one is you lose control of 1/3 of the exposure triangle. I do use it but only in Manual mode and changing light conditions, so I control both aperture and shutter speed.

Even though I would consider myself to be very technical, I don't or haven't adjusted any of the ISO settings on my camera in 2 years. The camera has been doing very well on it's own other than my telling it to focus on a particular subject in the foreground or background. If the camera has been using the auto ISO and you like these settings then don't adjust anything.

I usually use auto ISO but with limits depending on the camera body. ISO performance on current cameras is pretty amazing, so I let it float in what seems to be the camera's solid range.

I shoot Macro in the field using Auto ISO. Mostly bugs. Settings are F14, Shutter speed 1/250, Auto ISO limited to 2000 with speed light. I have only a few seconds at most to get the shot. Since with my camera (D500) noise is not a problem at ISO below 2000 all I have to do is aim and shoot.
When doing studio Macro I go manual. In this instance will set f-stop for depth of field and ISO some low value and shutter speed to get the exposure I want.
Auto ISO is just another tool to help get what you want under the circumstances.

Auto ISO is like any type of automation. It does it for you quickly when you don't have time but if you don't check what it's doing it may do something you don't want. Using Auto ISO the camera may set too high an ISO which would hurt your images. However, you must consider that there are situations where a very high ISO is the only solution even if the images suffer.

Thanks for this question Will. It is clear to me that many of the professionals and/or those with considerable experience that shoot wildlife and contribute here use auto ISO regularly. I have had difficulty with it blowing out highlights. However, the last time I experimented with auto ISO I switched from spot to matrix metering and had much better success. Which leads to the question: is the selection of the metering mode an important consideration when using auto ISO?

That is a great question.

It' not a philosophical choice.
Bob's right. With auto anything there are lots of situations where the camera's meter gets it wrong.
When you know what you are doing, full Manual is more consistent and safer.
