>>3511102Let's take your statement for example:
> image stabilizing has 3-4 stop rangeThis means that with image stabilization, you can reduce either of the settings up to 3-4 times, giving you a more desirable result.
Let's say you're taking a photo at ISO 1600, f/1.8 and 1/400s, and the image is still too dark. Let's assume you maxed out your ISO and your aperture.
With image stabilization (IS), you can increase your shutter speed from 1/400s to 1/200s (that's 1 stop), then 1/200s to 1/100s (that's 1 stop), and then 1/100s to 1/50s (that's 1 stop).
So that's three stops less than your original shutter speed setting, but you can now hand hold the camera longer and get more light in, giving you a brighter image.
I hope this gives you the gist of it. If not, let me know.
