I wonder though with a 28mm sensor, if we're moving it by 5mm in each direction to achieve stabilization, how many 35mm have good coverage on a 38mm wide rectangle? I can't imagine any DA lenses doing it (well, the 40 might), and certainly on any 35mm lens could result in softer edges or even vignetting where it wasn't seen before. Can always compensate by stopping down I guess, but that reduces the benefit of stabilization in the first place....
The full 5mm movement is rare. Most compensation moves much less. I've used the Maxxum 7D rather extensively and have not seen any sign of vignetting. As for stopping down, that's one of the reasons for stabilization. It allows you to use slower shutter speeds precisely so you can stop down more.
The important thing that gets lost in all this techno-babble is that it WORKS. I can hand hold a 300mm at 1/15 second, without a monopod.
