i just bought a sigma lens with ‘optical stabilization’ for my Canon Rebel camera. I had intended to buy one with ‘image stabilization. are these two the same thing with different manufacturers using different terms for the same feature?

Canon only offers “Image Stabilization” through it’s lenses, so in a sense optical stabilization is the same thing. If canon were to add “IS” through their camera bodies the high price “IS” lenses would go obsolete. You will be very saitisfied with your stabilized lense, they usually allow you to shoot your pics a few stops slower and get nice clear images.
canon offers – image stabilization
sigma offers – optical stabilization
These are two different terms for the same thing.
Image stabilization got its start in camcorders, and it was achieved by digitally zooming in on the subject. While this worked, it made the image look pixelated and blocky.
That’s why the term “optical image stabilization” came about: it’s saying that you’re not getting any of this reduced quality digital zoom crapola in your image, which is a good thing. Canon cameras use only optical image stabilization, whether or not it’s labeled “optical.”
Enjoy your new lens!
