Image stabilisation too often isn't! The increasing use of the moniker 'Image Stabilization' or 'Anti-Shake' to describe nothing more than a (noisy) high sensitivity mode has become annoying. It is, in fact, dishonest. http://www.dpreview.com/news/0701/07010501notimagestabilization.php

Very deceptive if not outright dishonest. Phil Askey of DPReveiw doesn't go far enough, though. The practice won't change without calling out the offenders by name. "Anti Shake DSP" is Casio's deceptive name for a simple high ISO mode. "Anti Blur Technology" is Sony's high ISO mode. Sony uses "Super SteadyShot" to describe their moving sensor stabilization method. Samsung has a legit "OPS" (Optical Picture Stability) system, but they also have "ASR" (Advanced Shake Reduction) which is just high ISO. Olympus uses the term "Digital Image Stabilization" for its high ISO function. Pentax does a little better job of distinguishing its "Shake Reduction," which moves the sensor, from its high-ISO "Blur Reduction," and its digital "Movie Anti Shake Function."

It depends. On some cameras, like my Fuji, "Anti-Shake" means that it bumps up the ISO (more noise) to get a faster shutter speed. This camera's sensors, however, have quiet low noise levels. All this is advertised. On other cameras, though, the ISO isn't bumped. The shutter speed and ISO remain the same, but either the lens or the sensor compensates for motion.

That's the point Ariel. Setting a higher ISO to get faster shutter speeds is not the same as physical image stabilizaton wiht either lens or sensor compensation). Whether or not the higher ISO has higher noise, it is a deception to call that a special image stabilization or anti-shake feature. Virtually ALL digital cameras can set higher ISO. Additionally, faster shutter speeds to avoid shake changes the composition in a way that physical IS does not. Physical image stabilization allows slower shutter speeds so that motion blur can be captured hand-held (eg. water falls), or vertical correction when panning a moving subject. Setting high ISO to get faster shutter speeds does not solve the shake problem in those cases.

You're right. The companies say it's anti shake because it looks attractive. Truth be told, it's just a nice way of saying that the camera can be set to a higher iso than worse cameras. And yes, I would so much love to be able to get a slower shutter speed with lower noise and still get a clear shot when handheld, and "anti-shake" could mean that but doesn't in my case. But faster shutter speeds are helpful when you want to freeze motion (a bird flying, for example). Whatever. Maybe a little deceptive, but both methods have their pluses.

True IS has bee around for years. Another word for it is "tripod". :)
