Canon has released a further firmware update for the EOS R5.
Firmware version 1.1.1 incorporates the following fix and enhancement:
1. When the RF 100-500mm f4.5-7.1L IS USM lens is attached, an image stabilisation effect of approximately six stops* is achieved through collaborative control with the in-lens image stabilisation.
2. Fixes a phenomenon in which the IS capabilities may be degraded when performing continuous shooting in cases where the RF 100-500mm f4.5-7.1L IS USM lens is attached to the EOS R5 running firmware version 1.1.0.
*Focal length 500mm, Based on CIPA (Camera & Imaging Products Association) standards.
You can download the update from Canon's support website.
This firmware update is for cameras equipped with firmware versions up to 1.1.0 and includes previous improvements and fixes. If your camera's firmware is already Version 1.1.1, this update is unnecessary. When updating the firmware of your camera, please first review the instructions thoroughly.
