Digicame-info (translated) broke the news just a few minutes ago: It appears that a new lens for the Canon EOS M system is around the corner. It should be an image stabilized 11-22mm f/4-5.6 lens, the EF 11-22mm f/4-5.6 IS STM. Unfortunately there are no more specs leaked for this lens, just that the filter diameter will be 55mm. I guess the lens will be very compact.
