Canon RF 24‑105mm f/4L IS

Full-Time Manual Focus Added You can now make constant manual focus adjustments in both One-Shot AF and Servo AF modes. This is especially useful for videographers and photographers who want precise control without switching focus modes. (Feature available when used with compatible cameras.) Focus Ring Can Now Function as a Control Ring The update allows the focus ring to be reassigned as a control ring, enabling silent adjustments to settings such as aperture, ISO, or exposure compensation. This is a major benefit for video shooters who want to avoid audible clicks being picked up by the microphone.(Feature available when used with compatible cameras.) General System Stability Improvements Canon has also refined internal communication and performance for smoother, more reliable operation across supported EOS R bodies.
