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.


Canon has ample on line resources describing how it works in their case.
Why not just call it IS and move on, folks?

Because "how does it work?" is an interesting question. I'd expect that
anyone who doesn't find it interesting will indeed move on. Canon's "ample
online resources" do not adequately describe how it works.
