I have a Sigma 17-70 on my Pentax K10D. How is this new lens different?
Of what use is a lens with a built-in optical stabilizer on a camera body with image stabilization?

It's more sharp and overall better than the old version.

"I have a Sigma 17-70 on my Pentax K10D. How is this new lens different?"
If the lens you currently own is a 17-70mm F2.8-4.5 DC MACRO, then the main differences are that the new lens is a third of a stop faster at the telephoto end, that its optical construction is different (17 elements in 13 groups instead of 15 elements in 12 groups), and that it has a built-in quiet autofocus motor.

Gives you the choice to use the stabilisation method that works better for you. Allows you to see the stabilisation effect in the viewfinder, which can help with the framing. Who knows, it might even work in synergy with the in-body stabilisation of the Pentax K10D, although this is highly improbable.

Zoltan - it doesn't. It's OR lens stabilization OR camera stabilization. you can't use both.

That's usually the case. This is why I wrote that it gives you the choice to use either the in-lens or the in-body stabilisation method. However, until the lens is released, we won't know for sure that the two methods can't work together in this particular case.

Actually - we know this. For synergy of body and lens stabilization you need completely different way of stabilizing the sensor - it should react on picture movement, not camera movement, so it's impossible to make any kind of double stabilization with a camera that doesn't support it since a day of release.
Also double stabilization if someone manage to achieve it is as effective as sensor-only stabilization so... there's no point of having it. Still the usual case is that double stabilization means worse pictures than without stabilization at all.
I know that it looks great on paper but reality is reality.
