Canon's revolutionary constant f/2.8 superzoom spanning 24-105mm, the first of its kind.
The Canon RF 24-105mm f/2.8L IS USM Z was released in 2024 as Canon's constant f/2.8 standard zoom for the RF system, covering the 24-105mm range — notably wider than the previous RF 24-70mm f/2.8L IS USM and extending to 105mm for portrait telephoto use. The 'Z' designation indicates compatibility with Canon's PZ-E2 and PZ-E2B Power Zoom controllers, which provide motorised focal length adjustment at selectable speeds for smooth video zoom transitions. L-series dust and moisture sealing is built in throughout.
The optical design uses 23 elements in 18 groups. Eleven aperture blades produce smooth bokeh. The 82mm filter thread requires a large-format filter set. At 1,430g the lens is substantial — the extended zoom range and constant f/2.8 aperture through 24-105mm account for the weight over the shorter 24-70mm f/2.8L IS USM. Minimum focus distance of 0.45m. IS is built in. The Power Zoom 'Z' mechanism accepts the PZ-E2 controller for motorised video zoom without manual barrel rotation. L-series dust and moisture sealing is built in.
The 24-105mm f/2.8L IS USM Z covers a significantly wider working range than the 24-70mm — the 105mm end provides portrait telephoto compression and head-and-shoulders framing that the 70mm end cannot achieve. The Power Zoom controller compatibility addresses a specific professional video workflow requirement: smooth, controllable zoom speed that manual-zoom designs cannot consistently replicate. At 1,430g the lens is the heaviest Canon RF standard zoom, appropriate for gimbal-mounted or monopod-supported professional video work.
The RF 24-105mm f/2.8L IS USM Z is a 2024 product; used availability is limited. Condition checks: IS operation, ring USM response, L-series sealing at the zoom barrel, Power Zoom motor function (if present), and 82mm filter thread for damage. The Canon RF 24-70mm f/2.8L IS USM provides the same f/2.8 aperture in a shorter range and lighter body at a lower price. The RF 24-105mm f/4L IS USM provides constant f/4 at lower weight and cost. Compatible with all Canon RF-mount bodies.
