Canon has patented a new wide-angle to standard zoom lens in Japan. It is the EF-M 15-50mm f/3.5-5.6 IS STM lens designed for company’s mirrorless interchangeable lens system.
From the patent application we can see that Canon is working on a new wide-angle to standard zoom lens with a maximum aperture range between f/3.5-5.6. If becomes available, it will be aimed at Canon EOS-M mirrorless cameras.
We can also say the upcoming optic will feature STM motor for silent and fast AF operation. Sure the IS designation refers to image stabilization technology.
