I'm just looking at these lovely "white" canon lenses, and they have Image Stabilizer.
Now, I know it stabilizes and image, and reduces the effect of camera shake, but:
How does the technology work?? |

A "corrector lens" hangs from a frame inside the lens. The corrector element shifts when the camers moves during exposure to compansate for the movement of the lens. Thus allowing a sharp focal plane. Basically, the corrector element is a parabola that reflects the image to a singe point.

so, would i be right with this:
a 'floating' element, that stays in the same place, even when the lens is moving with the photographer.
and this 'floating element' still directs the light to the same point on the sensor (or film) ???? |

yes and no. it does direct the light to the same point. But it does not float. Motion sensors tell the frame of the corrector element which way to move.

Konica/Minolta Dynax 7.The Dynax 7 Digital is also equipped with the same technically sophisticated and highly effective CCD Shift-type Anti-Shake function, which has earned an excellent reputation in the DiMAGE A1 (SLR- type digital camera with built-in lens). As the Anti-Shake function is built into the camera body and not the lens, it is effective for the entire range of Minolta AF lenses.
Cheaper lens prices? :)
