The RF 24-105mm f/4L IS USM is the do-everything L-series zoom for full-frame EOS R cameras, covering wide landscapes, events, portraits and travel with a constant f/4 aperture. It arrived alongside the very first EOS R in 2018 and remains a mainstay of full-frame RF kits.
Optical stabilization rated at 5 stops uses Dual Sensing IS for stills and Combination IS for video, working with the camera to steady handheld and walking shots. Nano USM focuses quickly and silently, so the lens moves from fast-paced events to quiet interviews without adding noise to the soundtrack.
Three glass-molded aspherical elements, a UD element and Air Sphere Coating control aberrations and flare, while focus down to 0.45m with 0.24x magnification helps with detail shots. At 700g with a 77mm filter thread, it balances well on bodies from the EOS R8 to the R5 Mark II.
