when the anti-shake is on, does the camera continuously move the sensor and your hands are moving, or does the sensor move only after the shutter is released?

i know how it works, but when, during the shooting process, does it actually start working.

thanks.

My understanding is that it waits untill the shutter opens to actually shift the sensor.

I read this on Mike Johnston's Sunday Morning Photographer column.

wow....how does it have enough time to do all those calculations in 1/30 of a sec.

impressive.

I'm guessing it is analyzing the movement before-hand and just waits to make the actual shift untill its necessary.

When shooting it has a meter showing how much camera shake it is compensating for (1-5 bars).

Only a matter of time before every DSLR has anti-shake in the body

Well, its really "the" selling point about the camera.

I think its brilliant, personally. I don't ever want to live without anti-shake again.

It does use a bit more battery power when activated, averaging somewhere around 350 shots on a charge. Luckily my memory card can't hold more than that (1gb)

After the anti-shake its a question of what you need/want/can afford on the body and whether to go with the 7d or 5d.

IMHO, any company that can come up with something as brilliant as anti-shake in the body deserves some business.

I'm no expert. But, it has something to do with a "feedback loop" if the camera is expecting movement and there is none to adjust for.

Other models with stabilization (movinglens elementsversus moving a CCD in the camera body) can also suffer from this problem (and I've seen arguments both ways on whether or not it "really" causes a problem in most conditions). It probably depends on your shutter speeds and the stability of the tripod.

hello, if you are being buffeted by high winds while on a tripod or if you have vibrations transmitted to the tripod, i think you can use the antimotion to good effect, but I've not yet tried this...it would be a good experiment to see what frequencies the sensor compensates for .....anyone from KM listening?

regards
