Canon a590IS ?

Post by mrosspa » 24 Sep 2011, 13:47

I was trying to find the spec. differences between an a590 and an a590IS. I can't find the difference.

What is the difference, and is it important?

"IS" means image stabilization. So the a590IS presumably compensates for camera shake when shooting at "low shutter speeds". For fixed camera positioning, as in book scanning, I doubt that the "IS" would be all that useful particularly if you shoot with a lot of light.

yep, tosborn has it. also the A490 and A495 are more modern cameras that may work for you.

If I recall, image stabilization can actually make results worse. It's usually better to turn it off with fixed camera positioning.

It all depends. But I can tell you that there is no option to have IS on the low-end canons. There isn't an A590 and A590IS, only an A590IS. Anything you see to the contrary is just lazy typing, probably from me.
