In-camera SLR sensor stabilization has been around the industry for several years now and yet, two of the major manufacturers, Canon and Nikon, have yet to jump on the bandwagon. There are a couple of obvious possibilities that have been talked about as to why. Both Canon and Nikon have their own stabilization technologies and licensing a stabilization technology from another company would be self-competing.
Another is that Minolta, the company that developed the in camera stabilization tech, has gone belly under and Sony has acquired the SLR division and produced a camera utilizing the tech, which they have re-branded to their own “Super Steadyshot” name. Licensing this technology would no doubt be costly and neither Canon nor Nikon would be likely to want to use Sony’s nomenclature.
