Me and a few of my friends were debating last night over a cup of coffee at our local coffee shop.  we debated why major brands like Canon and Nikon is not adapting sensor-shift technology but instead keeping a lens shift technology.

I did a bit of research at the Nikon and Canon website. Both seems to give similar explanations on why they are not adopting to sensor-shift VR.

Here are the Nikon’s explanation on why they adopted the lens VR.

1. Corrected finder image makes photo composition easy.
Because camera movement is compensated within the lens in use, you can see a clear finder image. This makes it easier to capture your subject in the focus frame and confirm composition. With a camera that corrects image blur inside the camera body, the image in the finder remains blurred.

2. Each lens is optimally tuned to achieve reliable correction.
Unlike cameras that only provide an internal image-blur function, every lens is optimised. As a result, you can shoot at shutter speeds up to three or four stops slower than would otherwise be possible.

3. Image information captured by the AF and metering sensors is corrected with in-lens VR.
This is a major difference from the in-camera VR. The result is faster and more accurate autofocusing and exposure metering.

4. Patterns of image blur are not the same with all lenses.
Image blur caused by camera movement differs with each lens used. This phenomenon is more noticeable when you use a lens with a longer focal length. So each lens should be finely tuned.

As for Canon’s explanation, you might have to visit their site for more details. The explanation in the L lens technology section has describe the superiority of IS.
