The RF 24-105mm f/4L IS USM from Canon is a wide-angle to short telephoto zoom characterized by its constant f/4 maximum aperture. Ideal for use in nearly any shooting scenario, this zoom is benefitted from a five-stop-effective Image Stabilizer to minimize the appearance of camera shakes for sharper handheld imagery. Benefitting image quality, the advanced optical design features a Super Spectra Coating, which helps to suppress ghosting and flare in order to improve contrast and color accuracy when working in bright and backlit conditions. Standard wide-angle to a telephoto zoom lens is designed for use with full-frame Canon RF-mount mirrorless cameras. Super Spectra coating has been applied to individual elements to minimize ghosting and flare for greater contrast and color neutrality when working in strong lighting conditions. Nano USM system utilizes both a ring-type USM and an STM mechanism to realize quick and accurate focusing that is also smooth and near-silent to suit both photography and video applications. This focusing system also affords full-time manual focus control when working in the one-shot AF mode. As a member of the esteemed L-series, this lens has a weather-resistant design that protects against dust and moisture to enable its use in inclement conditions.
