I'm trying to decide whether to get the new "Canon Powershot A590 IS" or the new "Canon Powershot A580".

The camaers are very similar except one has image stabilization and the other does not.

Is image stabilization worth it? I've heard that in order to get rock steady pictures, you still need a tripod or the camera has to be on a steady surface. Thanks!

The difference in cost between the A590 IS and the A580 is about $30.

Is IS worth $30?

Will you be carrying around a tripod with you everywhere you go? How much does the tripod cost? Can you afford to take the time to set up the tripod before the shot, and break it down afterward?

Will you always have a steady surfaceto place the camera on?

IS allows you to take photos at slower shutter speeds (in lower light) than you might otherwise. Will you always be taking photos of well lit subjects?

If you have IS and don't need it, you can just turn it off.

If you don't have IS and need it, you can't just turn it on.

I would agree. For $30 it'sa no-brainer

I understand that IS is "worth" about 4EV's? In other words, 4 shutter speeds slower, or4 f-stops smaller, or4 ISO stepsfaster, or any combination, than is possible without IS.

Is this correct?

Four might be a bit optimistic.

Yes it is invaluable in low light and long zoom use. Can you take great shots without it? Yes but in some situations you will need a tripod or something to support your camera. I would be willing to pay a lot more than $30 for the feature. C. W.

Good opportunities often occur in low light, and image quality suffers at high ISO. IS lets you keep it down lower. I have found IS invaluable, and a breakthrough in my photography.
