With all of the arguments about if in-body IS (like Olympus, Pentax etc) is better, worse or just different to in-lens IS (Canon, Nikon etc), I was wondering if it would be feasible to have a samll adaptor, similar in size to say a 1.4x converter, positioned between camera and lens with the function of adding IS to a non-IS lens.

Even if it were quite expensive I would expect a lot to be sold. To counter those who say it's better to have in-lens IS as it would be tailored to the needs of that lens, there could even be two versions, one for short telephotos and one for longer focal lengths, maybe 300 mm and up.

Probably just an idle thought, but I reckon there's a lot of people out there who can't afford to upgrade their lens collection, but would be very interested in one adaptor with that function.
