The Nikon Z 24-120mm f/4 S and the Canon RF 24-105mm f/4L IS USM are comparable f/4 standard zooms, but they fit different mounts, so your camera system decides the choice. The Nikon reaches a little farther at 120mm, while both offer a constant aperture and image stabilization in the lens or camera system.
Two lenses, two systems
Each lens is the maker’s premium general-purpose zoom for its full-frame mirrorless mount. You cannot simply swap one for the other, because Z and RF mounts are different. The real question is usually which system you use or are considering.
Both lenses cover the classic range from wide-angle scenes to short telephoto, which suits travel, events, family photos and documentary work.

What the differences mean in use
- Range: the extra 15mm on the Nikon helps when subjects are a bit farther away, such as stage performers or street scenes.
- Aperture: both give the same f/4 opening, so low-light performance depends mostly on the camera sensor.
- Stabilization: lens-based stabilization works together with in-body stabilization on many modern bodies, though the exact benefit varies.
- Ecosystem: the wider lens and accessory lineup of your chosen system often matters more than one lens detail.
How to choose
- Begin with your camera. If you shoot Nikon Z, the Z lens is the natural fit, and the same logic applies to Canon RF.
- If you are choosing a system, compare the whole lens lineup, not just this zoom.
- Check body features such as autofocus tracking, video options and handling.
- Try each in a shop if possible, noting the zoom ring, balance and hand feel.
- Think about what other lenses you want, such as a fast prime or a telephoto.
Handling and sealing
Premium zooms of this type are normally built with weather sealing and a smooth zoom ring, but the extent varies by lens. Read each maker’s page for the official sealing and control details. Also consider the extra control ring or switch layout, since you will use them every day.
FAQ
Can I use the Canon lens on a Nikon camera?
Not directly. Adapting between these mounts is generally not practical, so choose the lens made for your camera system.
Is f/4 enough for low light?
It is workable with modern sensors and stabilization, but f/2.8 zooms and fast primes are better for dark scenes.
The Short Version
These lenses are close in concept, so choose the one that matches your camera mount. If you are still deciding on a system, compare complete lens lineups and body handling, and confirm details on the makers’ pages.
