A standard zoom covering wide-angle to short telephoto perspectives, the graphite EF-M 15-45mm f/3.5-6.3 IS STM Lens from Canon offers a 24-72mm equivalent focal length range when used with APS-C-format EOS M-series mirrorless cameras. The optical design incorporates three aspherical elements, one of which is glass-molded and the other two are precision molded, in order to control chromatic aberrations and distortions throughout the zoom range. The lens placement has also been optimized, and coatings have been applied, to reduce flare and ghosting for increased contrast and clarity when photographing in difficult lighting conditions. Benefitting handheld shooting with slower shutter speeds, an Optical Image Stabilizer has been incorporated into the lens design to minimize the appearance of camera shake by up to 3.5 stops. A lead-screw-type STM stepping motor is also featured, which produces fast, smooth and near-silent autofocus performance to support both stills and video applications. For increased control, full-time manual focus operation is also available for making fine-tuned focus adjustments. Additionally, pairing well with the compact form factor of the EOS M-series of cameras, this lens also features a retracting design to shorten its overall length to just 1.75" long during travel and storage.
