Canon has released new firmware update 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.
