Canon patents ‘drop in’ image stabilization device for lenses

Image stabilization comes in two main varieties: in-camera and lens stabilization. But a third type of stabilization technology might be just around the corner. According to a patent uncovered by Egami, Canon is working to develop an external image stabilization unit that you can insert into the lens, between the focusing component and rear elements
According to the patent, which was originally filed in July of 2013, the device uses Canon-designed stabilization technology without altering the attached lens’ focal length or aperture range. Additionally, this technology will allow photographers to adapt their gear to specific needs. If you're looking to save on weight, leave the IS behind; if you need an extra stop or two, drop it in and you're good to go.
As for the optical components present in the IS drop-in, it's comprised of 6 elements in 4 groups.
While indeed interesting technology, there are limits to such a design. Most notably, this technology would not be compatable with older lenses not designed with a drop-in design. Furthermore, this leaves internal components of lenses much more vulnerable than enclosed image stabilization technologies.
There's no promise we'll ever see this as a concept, let alone a product, but it's interesting technology nonetheless and shows Canon isn't afraid to get interesting on the drawing board.
