Using the Auto ISO setting and setting minimum shutter speed

The Auto ISO setting will work on all the mode settings EXCEPT P,S,A,M, U1 and U2 modes. If you use any of the other modes on the dial or choose any of the 19 Scene modes that you have to choose from you can set your ISO to automatically increase as the need arises. If you choose to use Auto ISO mode I would recommend setting the limit of what the ISO will go up to. You will have to determine for yourself the highest ISO by determining how high you can go and still maintain the picture quality you desire. I do not use auto ISO myself but if I did the highest I would probably allow it to go would be 3200. You will also be able to set your minimum shutter speed in the same place in the menu allowing you to set the shutter speed to not go below what is needed to stop action in the shot or eliminate blur from shaky hands.

An example of when this may be helpful is when you start shooting pictures at your child's baseball game and as the game goes on the sun starts going down and the light gets less and less. By choosing the Auto ISO setting ahead of time as the sun goes down your camera will allow you to keep taking pictures by increasing the ISO automatically so you can keep on shooting. If you have it set to a certain ISO such as ISO 400, after the point the light gets past it's ability to capture the pictures you want, your pictures will just start getting darker. If you have chosen the Auto ISO setting you can continue shooting and the camera will increase the ISO as needed to allow you to keep capturing those special memories. As with changing any settings I would recommend doing it before hand so it doesn't catch you off guard at the game. Trying to change settings when you are under pressure to get the next shot is not the time to try and figure out what you need to do or how to do it.

If you would like to try this, here is how you do it.

Go to the shooting menu. The second one down on the left that looks like a camera
Next go to ISO sensitivity settings and press the right side of your toggle switch
Go to Auto ISO sensitivity control and turn it on
Next go down to Maximum sensitivity and press the right toggle button and choose the limit that you want and press OK
Next choose the minimum shutter speed that you think you can handle or is needed and press OK
You are now all set up and ready to go

Can you see how if you wait until the game and you are under presser that figuring out how to do this could get you all messed up.
Also remember that you may have to set the ISO higher than you might like to get the shot of your child. Sometimes you have to set the ISO higher than you would like because having a little noise in the shot is a better option than not getting the shot at all.
