Offering the quiet and smooth autofocusing benefits of a stepping motor for full-frame EOS DSLRs, Canon's EF 24-105mm f/3.5-5.6 IS STM Lens is a standard telephoto supporting the use of the Movie Servo AF mode with compatible cameras. Complementing the focusing precision is an equally apt Optical Image Stabilizer, which helps to minimize the appearance of camera shake by four shutter speed stops to benefit working with slower shutter speeds or longer focal length positions. This wide-angle to telephoto zoom lens is designed as a useful option for everyday shooting for both photo and video applications.
