PhotographyJam has picked up from a Canon white-paper their rationale for not going the Sony “in-camera” image stabilisation route

Some of Canon’s competitors have chosen to use in-body image stabilization. The technique involves moving the image sensor in a controlled fashion, based on signals from movement detecting sensors in the camera body. The obvious advantage of this system is that users have some sort of stabilization available with almost any lens they connect to the body. Short focal length lenses require smaller sensor deflections; 24 or 28 mm lenses might need only 1 mm or so. Longer lenses necessitate much greater movement; 300 mm lenses would have to move the sensor about 5.5 mm (nearly 1/4”) to achieve the correction Canon gets with its IS system at the same focal length. This degree of sensor movement is beyond the range of current technology. Short and “normal” focal length lenses need stabilization much less often than long lenses, so the lenses that need the most help get the least.

There is probably equal amounts of truth and spin going on here, I imagine Sony’s system for some scenarios works better and for others Canons provides the best results. It seems though Canon and Nikon are going to provide the greater quality where it counts for me. I see no great need for image stabilisation for normal shots outside of long focal lengths. Perhaps macro photography would benefit, I don’t do much of that. Low light/long exposure photographs suffer as much from motion blur than camera shake in my experience.

I actually believe in future we will see software playing a much greater part with algorithms able to remove camera shake and perhaps even motion blur if required.
