A patent for a new EF-M lens has appeared. We’ve been told that there will be 3-5 new lenses coming for the EF-M mount in 2016 and at least one will be a new kit lens. This patent is for an APS-C sized sensor and the optical formula is for an EF-M 16-80mm f/2-6. This concept definitely fits what would be considered a kit lens.
