Canon RF 24-105mm f/2.8 L IS USM Z Full-Frame Lens for RF-Mount {82} with Tripod Foot

Canon's 24-105mm f/2.8 L zoom that broke the aperture rule

No 24-105mm zoom had ever held f/2.8 constant across its entire range before this lens arrived. Canon's RF mount made it possible, and the result is a lens that replaces two common workhorses - the 24-70mm f/2.8 and the 24-105mm f/4 - without forcing the compromises that defined both. The 23-element, 18-group optical formula includes four ultra-low dispersion elements and three aspherical elements to keep chromatic and spherical aberrations controlled at wide apertures across the full zoom range.

Dual Nano USM motors drive autofocus that's fast and nearly inaudible, which matters both for event shooting and video work. On the video side, the click-less iris ring allows smooth aperture pulls during recording, the internal zoom design keeps the barrel length fixed for gimbal balance, and focus breathing suppression keeps the angle of view consistent during focus shifts. Optical IS delivers 5.5 stops of correction standalone, or up to 8 stops with Coordinated IS on compatible IBIS-equipped bodies - useful at 105mm where camera shake becomes harder to manage handheld.

At 2.9 lb and 199mm long with an 82mm filter thread, this lens carries real weight, but the tradeoff is a zoom range that covers environmental wides through genuine portrait-length compression, all at f/2.8. For shooters who have been choosing between reach and speed for years, this lens ends that conversation.

Who It's For

Wedding and event photographers who move between wide ceremony coverage and tighter candid moments will appreciate holding f/2.8 at 105mm without touching exposure settings. Videographers in hybrid production setups gain from the click-less iris ring, power zoom adapter compatibility, and parfocal tracking during zooms. Portrait photographers get 105mm compression plus consistent shallow depth of field at every focal length, not just the long end. Documentary and travel shooters who rely on a single lens across varied conditions benefit from the 5.5-stop optical IS and an 84° to 23°20' angle-of-view range that covers most situations without a bag change.

FAQ

Is the RF 24-105mm f/2.8 really constant f/2.8 across the entire zoom range?

Yes. This is the world's first 24-105mm zoom to hold f/2.8 from 24mm through 105mm. The RF mount's large diameter and short back focus made this optical configuration possible without the size penalties that would have been required on previous mounts.

How does f/2.8 change the way I shoot compared to a 24-105mm f/4 lens?

One full stop of light translates to lower ISO in dim conditions, faster shutter speeds to freeze motion, or shallower depth of field for subject separation. At 105mm, the difference in bokeh between f/2.8 and f/4 is substantial for portrait and selective focus work.

What's the autofocus like for video?

The dual Nano USM motors deliver near-silent focus operation with electronic parfocal focus that maintains focus during zooming and focus breathing suppression that keeps your angle of view consistent during focus shifts. The click-less iris ring allows smooth aperture pulls during recording without audio artifacts.

How much image stabilization do I actually get?

Optical IS alone delivers 5.5 stops of correction. Pair it with a compatible EOS R body with IBIS and Coordinated IS stacks those systems for 8 stops total, which matters most at 105mm where handheld stability becomes harder to manage.

Does this lens work with Canon's Power Zoom Adapter?

Yes. The PZ-E2 adapter attaches without tools and enables electronically controlled zoom for video work. The PZ-E2B adds a 20-pin port for professional cinema and broadcast accessories.

What's the weight and length compared to a 24-70mm f/2.8?

At 2.9 lb and 199mm long, it carries real weight due to the extended 105mm reach. The included tripod foot is recommended when mounted on a tripod to prevent lens sag on the camera mount.

Can I use the iris ring for still photography on any EOS R camera?

The iris ring for still photography only functions on EOS R bodies introduced in 2024 or later. Video iris control works with earlier models including the EOS C70 and R5 C cinema cameras.
