The confusion perhaps results from the fact that these image-stabilization methods use devices called gyrosensors. A gyrosensor is not a gyroscope; it contains nothing that spins, and without spinning you can't have a gyroscope.


So, would you say that a ring laser gyroscope is really not a gyroscope
at all?


This all sounds like an endless and pointless terminology quibble.


It's really a discussion about how the things work. Many users in this thread clearly believe there are actual gyroscopes in all these IS lenses. I don't.



True .. and the best way to end this is to refer to a definitive source (e.g., Canon) vs. a bunch of folks trying to invent a description.
