Does Lens Image Stabilization really work? My pic not clear at 1/30 Second, but is clear at 1/60.?

I have CanonA720 IS camera, did tests at the shortest focal length outdoors in the shade. I am not the world's steadiest person! I'm using the 'continuous' option for image stabilization. When IS turned off, I don't see much of a difference in the LCD screen.Does Lens Image Stabilization really work? My pic not clear at 1/30 Second, but is clear at 1/60.?
You can't judge sharpness on the tiny LCD screen. You need to get to a full-size monitor or make some prints.





But, the short answer is that yes, optical image stabilization really does work, but it's not a miracle cure if you're really shaky!





It also works better at the longer focal lengths, where shake is magnified; it's has less apparent effect at the wider (shortest) focal length.Does Lens Image Stabilization really work? My pic not clear at 1/30 Second, but is clear at 1/60.?
Sorry buddy...I was going to ask about your shutter speed, but this is point and shoot, so I dont know. Sorry.
This is just for you to ';see'; the difference with image stabilization on and off. Place a newspaper on a wall outside in the shade taping all four corners. Zoom the lens of your camera out all the way to its most telephoto position and stand about six feet away from the newspaper. Use the same area of the newspaper for each of these shots. Make one image with image stabilization on and the other off. Do NOT make your comparisons using the small LCD screen -- you will NOT see the difference -- place both images on your computer screen or make a print of both. Make sure the newspaper is in the shade so that the camera must pick a relatively slow shutter speed, and handhold the camera -- NOT on a tripod. :鈥?
I use cameras that have sensor based image stabilization, they work very well.





That being said, image stabilization is not a miracle worker, you still need to hold the camera as still as possible. Try holding your breath, keeping your elbows tucked in to your body and leaning against something solid. That should take care of your problem.
