Firmware update for Canon RF 70-200mm f/4 L IS USM lens

Canon has issued Firmware Version 1.1.0 for its RF 70-200mm f/4 L IS USM lens, which provides two useful performance improvements.

The first fix 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. The second improves an issue in which the background is not blurred when performing slow panning with the IS (Image Stabilisation) mode set to Mode 2 or Mode 3.
