Canon has released new firmware for the Canon RF 70-200mm f/4L IS USM. This firmware update adds full-time manual focus when used with the EOS R3, EOS R5, and EOS R6.

The update also fixes an issue in which the background may not blur when using slow panning on mode 2 or mode 3 image stabilization.

Firmware Version 1.1.0 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.

  1. That already received the FTM feature in a previous update, you do have to enable it manually in the menus, though.
    Thanks - but as I know (and tried) manual override does not work in Servo-AF-, only in One-Shot-Mode and half-pressed shutter release button. For example my adapted 400mm f4 DO II provides this feature with the R5 in all AF-Modes. That's what I am missing in the RF 100-500.
  2. Update/clarification: setting the electronic full-time mf feature "ON" (R5 purple AF menu, page 5) enables mf focusing in all AF modes with the RF 100-500. Done so, everything works fine.
