Not sure if you're suggesting that Canon are adopting in-body stabilization or not, however the news post only mentions an improved in-lens stabilization method. My thoughts are that Canon would have to be dragged screaming and kicking into introducing an in-camera system for dslrs.
Its about time Canon caught up to Pentax. Laggards!All kidding aside, in-body stabilization is pretty fantastic.
"The technology will be incorporated in an interchangeable single lens reflex (SLR) camera lens planned for commercial release before the end of 2009."
And my guess is it will be incorporated into "every DSLR Canon develops" from now on.
After years of insisting that "lens based stabilization" is better, Canon has thrown in the towel and joined three other manufacturers in adding sensor based stabilization to their newest DSLRs.
This tells us two things:
So, Canon was pretty smart to finally make this move. And they were also pretty stupid for waiting so long to do it.
OK.... this means Olympus, Sony, Pentax, and now Canon will all have in body IS in their DSLRs.
The only question left is... will Nikon finally see the light?

This tells us two things:
- Canon felt like they were losing sales by leaving this feature off their cameras
- This could help Canon sell their non IS lenses

Er, do you want to read the quote again?

No, the only question is .. when will you learn how to read stuff?
It is a lens stabilisation system, plain, simple, and there in black and white.

I'm not sure but the OP might have been referring to the fact that Pentax's in camera shake reduction system has been able to compensate for rotational movement for at least one generation - rather than implying Canon's new system is in-body (which is clearly isn't).
I'm not sure whether Olympus' and Sony's systems can also compensate for rotational movement or not.

Canon's rotational stabilization corrects the rotational movement in an axial plane, while Pentax's corrects rotational movement that occurs in sensor's plane. The two systems stabilize different rotational movements.

The innovation in Canon's Hybrid system is nothing to do with rotational movements; all IS systems compensate for pitch and yaw. Pentax's adds roll, in contrast Canon's adds correction for vertical and horizontal shift . This means it should work even at macro distances - something no current IS system is really good at.

All systems compensate for rotational shake. Rotation around the x and y axes. If they didn't they would be mostly useless since that shake is the one that dominates the blur caused by shake for most kinds of photography.
Pentax have claimed they also can stabilise rotation around the z (lens) axis. It's unclear to me how much of a problem this shake is in reality. Perhaps at UWA focal lengths and very slow shutter speeds, particularly if poor technique is used. Lens IS can never correct this "roll" shake, it's an advantage reserved to sensor IS.
Canon's Hybrid (strange name...) IS corrects also for translational shake, a shake that doesn't matter at low magnifications (far distance) but is a problem with macro. Since it's only possible to measure acceleration, not velocity, I suppose it depends on the shooter cooperating and shaking around a point that doesn't move relative to the subject, for some time before the exposure. Then it may be possible to make a guess at a zero velocity reference and knowing subject distance correct the shake.
The effect will be a steady subject but motion blur (from the shake) in the background and foreground!
If Canon are right that this is a world's first, then Sony are wrong when their marketing claims they use subject distance information to improve SSS performance.

Hi Andy,
Could you please explain the difference between pitch and yaw as opposed to vertical/horizontal shift?
Is it shift as in "tilt and shift" ?
cheers,
bazz.

Zooms? pfffft!
Thanks for the thorough explanation.

Not at all, Canon's claims are quite specific. The relevant caveat is this one:

Yaw and pitch are rotational movements, and they make the lens point at a slightly different angle - like rotating a camera on a tripod head.
Shifts are translational (left/right, up/down) movements with the lens still pointing in the same direction - like moving a centre column up and down.

Well, you're not too bad at lens reviews either. ;-)

Yes. On the other hand, if Sony used the distance info for correcting shift shake, their marketing department must be utterly incompetent for not touting it like Canon did in this press release.

I am not familiar with that SONY claim "using distance information for SSS", sunce only the "D" lenses can provide this information... SONY's system uses the focal length information, needed to calculate the amount of sensor shift correction needed for specific camera angular deviation.
AFAIK - SONY SSS does senses and corrects both angular and planar (X,Y) shifts.

Sony fans have linked to marketing documents from Sony claiming they use FL, distance (for D lenses) and aperture(!) for the SSS. And complained that DPR used a Minolta lens without D info for their SSS tests.
That's unlikely. Canon advertises this as a significant breakthrough and so would Sony IMHO if they had the technology. Mentioning the aperture (which has nothing to do with stabilisation) is a clear give-away that it's just the marketing department that has smoked something unhealthy.
Anyway, it would be possible to demonstrate: Shoot a static macro subject at 1:1 with a D lens and a non-D lens, say 10-20 shots of each, stopped way down and at a shutter speed that just barely keeps the subject sharp. Have some specular highlights in the background which are still not too blurred out by DOF. If Sony used distance, the images shot with the D lens would show a sharp subject against a shift-shake-induced motion blur in the background.

Canon is not going to give up (and neither will Nikon) the 40-50% premium in-lens stabilization earns them. They take an $800 lens, put in $20 worth of electronics and lens mounts and up the price to $1200. That's too valuable to lose.Its about time Canon caught up to Pentax. Laggards!
Something wrong with your interpretation of what was said by Canon and I quote " The technology will be featured in interchangeable single lens reflex (SLR) camera lens planned for commercial release before the end of 2009 ". There is nothing being done with the camera bodies. This specifically states lens .

Great news for Canon users. Now they can purchase lenses in focal lengths they already own just to get the latest generation of IS. Man, it would be nice if there was a way you could upgrade the camera itself and get the latest gen-IS without having to re-purchase lenses...oh, uh, wait a minute... never mind.
