Is image stabilization really necessary in a point and shoot digital camera?

sorry...wrong choice of words. meant focus ability.

Even if your camera has AI Servo focusing, to help track an object, you either have a fast enough shutter speed or you don't. It does however, help prevent blurry pictures from being out of focus.

Sorry again...my point was that a "Fast" shutter such as 1/1600sec speed is not needed for low-light or night pictures as its the exposure time would be to short to capture anything even if your using a high ISO setting.

You could allways increase the apature and ISO to capture something moving fast is the lighting wasn't great.

I think you mean if the lighting was good, because if you have poor lighting conditions and try to use a fast ISO, pictures will be very dark. On the opposite, in dark lighting with no flash, the aperture stays open longer to gather more light, however it makes pictures more blurry if you dont have a tripod or other means of keeping the camera still.

Actually, I think his comment is accurate. High ISO is more sensitive to light, therefore allowing for higher shutter speeds. The larger the aperture, the more available light allowed in, which would allow for faster shutter speeds.
I think you mean the shutter stays open longer in dark lighting, not the aperture. It's slow shutter speeds that cause the blur. The aperture setting is pre determined (when you press the shutter) based on the light that's metered by the camera.

No, I meant if the lighting was bad... You increase the film speed, to something like 1600... If the lighting is good you want around 80 ISO...

With a high ISO you can take photographs with a slower shutter speed, which is often an advantage – in bad light

Yeah, You'd want a big apature... Yeah, You would need a tripod

Sorry, not being an ass, but I think its important to understand for good images.

High ISO allows for faster shutter speeds due to the sensitivity of light. You can really only take good images with slow shutter speeds using a tripod or with IS and reasonable shutter speeds.
High ISO is a huge advantage in low light, but normally at the cost of lower quality images. This is where high end camera's really shine...Good quality even at ISO 3200.

Yeah, You'll need a pretty decent camera to have good quality images with a high ISO...
