The EF-M 28mm f/3.5 Macro IS STM from Canon is a 44.8mm-equivalent lens designed for APS-C-format EF-M-mount mirrorless cameras. Characterized by its 1.2x maximum magnification and 3.7" minimum focusing distance, this sleek lens is further distinguished by its integrated Macro Lite LED to provide additional illumination to close-up subjects. Aiding its ability to reproduce small subjects at greater than life-size, the optical design incorporates one UD element and two aspherical elements to reduce chromatic and spherical aberrations in order to provide a high degree of sharpness and clarity. A lead screw-type STM stepping motor also benefits handling by producing fast, smooth, and quiet autofocus performance to suit both stills and video applications. This AF motor can be manually overridden at any time by turning the dedicated focusing ring for making fine-tuned adjustments. Additionally, suiting the sleek stature of the Canon EOS M-series of cameras, this lens also sports a lightweight form factor and retractable design. One Ultra-Low Dispersion element is used to control chromatic aberrations and two aspherical elements are also featured, including one double-sided aspherical element, to minimize spherical aberrations for increased clarity and sharpness. Lead-screw-type STM stepping motor offers fast, quiet, smooth, and accurate autofocus performance that is ideal for video recording as well as still shooting.
