My new D5100 offers the Auto ISO mode and I'm just wondering if anyone uses this mode and if so, what advantages does it offer?

The advantage of Full Auto is that the camera decides ISO, shutter duration, and aperture. You only have to point the camera.
The disadvantage of Full Auto is that the camera decides ISO, shutter duration, and aperture. You only get to point the camera.
As Sinatraman explains below: Auto ISO allows camera to select ISO (based on available light) when in manual, shutter priority, or aperture priority.

actually not to disagree with my fine nikon friend here, but auto iso lets the camera determine the iso setting based on how much light and the f-stop and shutter speed you set in manual mode or the shutter speed youset in s mode orf-stopina mode.if you are shooting where their isn't enough lite for the settings you have set, it will automaticaly raise the iso untill the proper exposure is reached. for a better explaniation then my confusing, rambaling one, check your manual.

Full Auto is a good place to start with a new camera. Read the manual and read online articles about adjusting ISO. I prefer to keep ISO low, so I don't have it on Auto. Of course, it depends on lighting, among other things.

I have the D5100 also and use the Auto ISO mode when I take photos of the cats at our shelter. I set it so it goes no higher than an ISO 6400 (camera is good about noise) and shutter speed of 1/125. I use Aperture Priority and can set it however I want, usually 4.5. The lighting at the shelter leaves a lot to be desired and each room is different so it makes it easier. Cats do not model for me (usually) so I don't want to be messing with settings all the time. But, I can set the aperture to whatever I want. I have used it here at home as well, sometimes the ISO is set to high and the SS is always at 1/125. I am very happy with it.

Thanks for all your comments on the Auto ISO mode.
Over the weekend I put it into practice. I went to my gdaughter's basketball game to take some pictures. I had no idea of the conditions but suspected the lighting might be a challenge and I would have no time in the game to experiment.
I ran in the P mode with Auto ISO and set the shutter to 1/800 to freeze the action. The camera set itself to ISO 3200 and,for my first attempt got a few half decent shots. If I had tried to choose the settings I would still be at the game experimenting.
AUTO takes control, but in certain situations, it saves the day.

Bryn Do you understand what ISO does, Speed Does, and F stop does? With an understanding of these you would not be experimenting.
In a gym or other settings the first thing you do IMO is decide what you want to do. Gym catch action, if so you need speed at least 500th of a sce, Gym a modest degree of depth of field, so you need at least f4 or f5.6. You set your camera to these parameters and then set the ISO so that you accomplish this. Take one shot look at it and adjust from there, but the adjustments would be minor.
On Auto the camera is doing all this.
Do my fellow UHHers agree with the above analysis?

This is Ken Rockwell's setting for Auto, which he uses.
" I set ISO 6,400 as the maximum because the D5100 still looks great at ISO 6,400. If you set a lower speed, the D5100 will start shooting at slower speeds when it could have kept the speed up at a higher (and still clean) ISO.
I set the Minimum shutter speed depending on my lens and subject.
For family, people, action and kids, I set 1/125. For sports you might want to set 1/250 or 1/500. This is the speed the D5100 will try to hold by increasing the ISO, and below which the D5100 will shoot at the highest ISO you set above.
For shots of still subjects, I set this to the slowest speed at which I can hand-hold sharply. For me, that's 1/8 with VR wide-angle lenses, and 1/30 for VR telephotos."

Ken has a steady hand, I could never hand hold at 1/8, I did some hand held at 1/15 but that was when I was a real young guy!

I agree, I have mine set at 1/125!!! I do like the auto, it has its place, that's for sure.

Bet they didn't have VR then.
They claim a 4 stop improvement with VR II. So 1/8 with VR is equivalent to 1/125 without.
No special skill there.
