Recognizable by its truly thin profile, along with an advanced autofocus motor, the EF-S 24mm f/2.8 STM from Canon is a 38.4mm-equivalent prime designed for APS-C-format DSLRs. Its optical design features one aspherical element, which helps to reduce distortion and spherical aberrations for high sharpness and clarity. A Super Spectra coating has also been applied, which helps to minimize lens flare and ghosting for improved contrast and color fidelity in bright lighting conditions. Additionally, benefitting both photo and video applications, an STM stepping AF motor is used to realize quick, accurate, and near-silent autofocus performance.
