Spanning a flexible wide-angle to short telephoto range, the EF 24-105mm f/3.5-5.6 IS STM from Canon is a useful zoom for a wide variety of shooting applications. Featuring two aspherical elements and one ultra-low dispersion element, both spherical and chromatic aberrations are well-controlled in order to realize a high degree of sharpness and clarity. A Super Spectra coating has also been applied to reduce lens flare and increase contrast and color fidelity when working in bright lighting conditions. Benefitting both photo and video applications, an STM stepping AF motor is used to realize quick and near-silent autofocus performance along with full-time manual focus override. Additionally, a four-stop-effective Image Stabilizer system is also featured and minimizes the appearance of camera shake for sharper handheld shooting.
