A standard zoom covering short wide-angle telephoto perspectives, Canon's EF-M 15-45 mm f / 3.5-6.3 IS STM lens offers an equivalent focal length range of 24-72 mm when used with EOS M format APS-C series of mirrorless cameras. the optical design incorporates three aspherical elements, one of which is molded glass and the other two are precision molded, in order to control chromatic aberrations and distortions throughout the zoom range. the placement of chromatic aberrations and distortions over the entire zoom range has also been optimized. the placement of chromatic aberrations and distortions over the entire zoom range has also been optimized. the placement of chromatic aberrations has also been optimized.

To benefit manual shooting with slower shutter speeds, an optical image stabilizer has been incorporated into the lens design to minimize camera shake in up to 3.5 stops, an STM stepper motor with a forward screw type is also included, resulting in fast, uniform and almost silent autofocus performance to support still images and video applications, and full-time manual focus operation is also available for greater control to make precise focus adjustments, combining well with the compact format of the camera's cameras to make precise focus adjustments, and combining well with the compact format of the camera's cameras.
