One problem with Canon IS that it must be turned off when the camera is on a tripod.
Otherwise it create its own problems. Vibration is actually introduced as it is
predictive of motion!

This is not true of all IS lenses.
Certain lenses have an

- how many millimeters is the sensor shifted for stabilisation?
as a side note:
is it shifting horizontally and vertically only? Overlaying these two
movements you can move diagonal as well. But you can't compensate
They do that at the expense of image smear. That would not be good for
stills.

I read the article about the new Minolta in pop photo, but thinking back
now I am confused by something. I don't have the magazine here to
check, but I swear they said they put a 500 mirror lens on the camera
and that the image stabilized through the viewfinder when they engaged
IS. How could
I would have thought that a maximum sensor shift of 1-2mm would be sensible to give
1-2 stops improvement. It's about 10% of the linear image dimension. Anything more
than this wouldn't be compensating for camera shake, it would be used for earthquake
stabilisation.

Hoepfully you are young enough to see your wish come true. ;o)

MT - how many
That seems unlikely, it would be far cheaper to just do it digitally.

Do you mean electronically? That would not work. Image stabilization
can only be done mechanically, either at the lens or on the film/sensor
plane.

Now, Rob, think about what you just said.
No one has claimed that Pentax is going to retrofit IS to the *istD. If
they build a camera with IS in the body they can well choose a sensor
that can do that. Remember the rumor I reported here that Pentax is
working on designing and producing their
