This may sound like a strange question, but anyway: you have to following hypothetical situation:
There's an object I want to photograph and there's not too much light. Focal length is 24mm, optimal shutter speed is 1/6, aperture is f/4. Thanks to the image stabilization it's possible here to take in most cases an unblurren picture. Now I switch to a lens that allows f/2.8 @ 12mm, but without image stabilization. Now I take a picture of the same object, same light conditions, but I move closer to it, so it'll have the same size on my picture. Due to the larger aperture I can lower my shutter speed to 1/12. Due to the shorter focal lenght this should also result in an unblurren picture. Now my question is, is my way of thinking correct, will I get pretty much the same results taking that picture @12mm, f/2.8, 1/12 and @24mm, f/4, 1/6 OS?
