Canon Patent Application: Mirrorless Cinema Zooms
While these at first look like they are high end kit zooms for mirrorless, they are simply too complex and have an image circle of 14mm which is not Canon's usual image circle for APS-C (13.66mm). This and the lens complexity makes me believe these are for cinema applications on the RF mount. If not, then these are extremely high end RF APS-C zooms.
