Firmware update for Canon RF 70-200mm f4L lens


Canon has released firmware version 1.1.0 for the RF 70-200mm f4L IS USM lens, which incorporates the following enhancements and fixes:

1. Adds an electronic full-time manual focus function (a function that enables constant manual focus adjustment in both One-shot AF and Servo AF), which is enabled when using the EOS R5, EOS R6, and EOS R3 cameras.

2. Improves an issue in which the background is not blurred when performing slow panning with the IS (Image Stabilization) mode set to Mode 2 or Mode 3.

Firmware version 1.1.0 is for lenses with firmware up to  version 1.0.8. If the lens' firmware is already version 1.1.0, it is not necessary to update the firmware.

You can check the firmware version of the lens from the camera menu. Refer to the camera instruction manual for how to check the current firmware version. Before starting the firmware update operations, please be sure to check the procedure in accordance with the instruction.

Canon teases new hybrid lenses

They are able to perform multiple roles and harness technology from Canon’s broadcast, cinema and existing RF lenses to make for a truly versatile range. The first two lenses in the range are the RF 24-105mm f2.8L IS USM Z , launched in November 2023, and the RF 35mm f1.4L VCM lens , announced earlier this year in June.

RF 28-70mm f2.8 IS STM announced

Canon Europe today announces the RF 28-70mm f2.8 IS STM, a new lightweight lens designed to be a next step for photographers wanting to upgrade from their kit lens.   Designed for a variety of shooting scenarios, from portraiture to street and travel, the fast f2.8 constant aperture throughout the zoom range is ideal for shooting in low light conditions, capturing everything from fading ‘blue hour’ light to dimly lit indoor scenes. Built with reliability in mind, this weather-resistant lens also allows for shooting handheld at slower shutter speeds in lower light environments with optical image stabilisation of up to 5.5 stops.   Measuring just 92.2mm in length when retracted and weighing 490g, this latest lens is among the lightest of its kind.

Firmware updates for EOS R1 and R5 Mark II

Canon has released new firmware for its flagship EOS R1 camera (version 1.0.2) as well as the EOS R5 Mark II (version 1.0.3), both of which offer the following enhancement and fix: 1. Optimizes the timing of the camera's display of its internal camera temperature warning indicator. 2. Fixes an issue that may interfere with the camera's ability to focus properly when using AF (autofocus) in certain zoom ranges. For the EOS R5 Mark II, Canon advises that if the camera's firmware is Version 1.0.1, you should update the firmware with only one memory card inserted into the camera. You should always read the instructions that come with the firmware update, as there are often details specific to that update, as with the EOS R5 Mark II (above).
