RF 24–105mm F4 L IS USM Overview

Compact, High-quality Lens with Broad Zoom Range for the EOS R System.

Compact and Lightweight

A dramatically compact 24–105mm f/4 lens, the RF 24–105mm F4 L IS USM packs a broad zoom range and a bright maximum aperture into a well-balanced, refined design that balances comfortably on the EOS R camera’s body.

54mm Large Diameter and Short Back Focus

The RF mount on the EOS R camera enables large diameter elements throughout the lens, including the rearmost element. This large diameter, coupled with the camera’s short back focus (the distance from the back edge of the lens to the surface of the image sensor), helps increase the flexibility of optical design, resulting in incredible brightness and image quality and contributing to the RF 24–105mm F4 L IS USM’s conveniently compact size without compromising performance.

Ideal Zoom Range for All-day Photography

With a zoom range encompassing wide angle, normal and telephoto, the RF 24–105mm F4 L IS USM excels in a variety of shooting situations, offering amazing versatility with the turn of a zoom ring. For example, with the RF 24–105mm F4 L IS USM, the EOS R camera can go from shooting landscapes to interiors and portraits without a single lens change. In countless situations where the light and subject are constantly changing, the RF 24–105mm F4 L IS USM lens is ready to go.

Bright, Constant f/4 Zoom Lens

The RF 24–105mm F4 L IS USM lens features 3 aspheric and 1 UD lens element to help correct aberrations, distortion and astigmatism, delivering sharp and dynamic images with excellent detail and contrast across the image frame and throughout the zoom range. Plus, it has a 9-blade circular aperture for beautiful, soft backgrounds.

First L Series Lens with NANO USM

High-speed Autofocus with NANO USM for Still Shooting

The RF 24–105mm F4 L IS USM uses Canon’s NANO USM system for the first time in an L series lens. NANO USM combines conventional ring USM and STM (lead-screw type) AF, and features a diminutive chip-shaped ultrasonic motor that’s engineered to help deliver high-speed, smooth, precise and near-silent operation, plus full time manual focus (when using One-shot AF).

Smooth and Quiet Autofocus for Video Recording

Another benefit of NANO USM is that it’s nearly silent. This means smooth and silent AF transitions that are ideal for video recording.

Control Ring for Direct Setting Changes

The RF 24–105mm F4 L IS USM lens incorporates a control ring on the lens barrel that can directly adjust numerous settings including shutter speed, aperture, exposure compensation and more. Located towards the front of the lens and effectively adding a third dial to the EOS R camera’s main dial and quick control dial, the control ring has a tactile, easily distinguished surface and features a clicking mechanism that provides tangible feedback for confident use while looking through the viewfinder. For photographers and moviemakers who would prefer a silent control ring, the clicking mechanism can be removed by a Canon service provider for a fee.

Optical Image Stabilization at up to 5 Stops* of Shake Correction

The RF 24–105mm F4 L IS USM lens is designed to work in conjunction with the EOS R camera, with both the camera and the lens sharing data to dramatically reduce camera-shake blur, regardless of the situation, whether shooting video or stills. With up to 5 stops* of stabilization, it delivers impressively clear results.

12 pin Communication System

High-speed Communication with the EOS R Camera

Designed to quickly process data, the RF 24–105mm F4 L IS USM features a 12 pin communication system that is the fastest yet for a Canon lens/camera combination. This accelerates AF, Image Stabilization, the Digital Lens Optimizer and more, helping to simplify complex operations and provide a quick and reliable user experience.

Lens Information Display

Another helpful feature, the EOS R camera can display lens information right in the viewfinder, making it easy to confirm the lens’s focal length without looking away from the subject at hand.

In-camera Digital Lens Optimizer

The EOS R system’s 12 pin communication system enables the Digital Lens Optimizer, which works in-camera to combat aberrations and image deterioration, especially in the edges of the image frame when shooting at a large aperture. Data from the RF 24–105mm F4 L IS USM lens is transferred automatically to the camera body, facilitating near immediate correction for clear, detailed images.
