Canon plans for future RF 70-200mm f2.8L IS USM lens firmware update

Canon plans to release updated firmware for the RF 70-200mm f2.8L IS USM lens in January 2020 to fix an identified and reported issue when using the 200mm end of the focal range. The statement, issued by Canon, gives further details as follows:

"It has been confirmed that when using the RF70-200mm f2.8L IS USM to perform AF shooting to capture a subject at close-range with the focus distance approximately set to the tele-end (200mm), the image may become slightly front-focused.

"New firmware with improved focus accuracy is scheduled for release in the beginning of January 2020, and once the preparations are completed, we will post the information on our website."

Firmware updates for two RF lenses

Firmware update version 1.0.4 for the RF 24-70mm f2.8L IS USM and firmware update version 2.01 for the RF 24-105mm f4L IS USM have been released.

These updates incorporate the following enhancement:
- Reduces colour unevenness when capturing images using long (Bulb) exposure mode with the EOS Ra. (Manual focus cannot be activated during exposure. And performing zoom operations during exposure, the subject may be out of focus.)

The firmware version of the lens can be checked from the camera's menu screen.
You can download the firmware update from the Canon website – select the tab for RF lenses and select the relevant lens from the list.

Firmware update for EOS R

Firmware update version 1.6.0  for the Canon EOS R offers the following enhancements and fixes:

1. Support for the RF 85mm f1.2L USM DS lens has been added.
2. Corrects a phenomenon in which the function or setting value assigned to the control ring may change when the control ring is operated in Eco mode.
3. Corrects a phenomenon in which the camera may stop operating properly during 'Auto transfer' when using Camera Connect with a Wi-Fi connection.
4. Corrects a phenomenon in which high-speed synchronisation with use of an external flash may not operate properly depending on the camera's setting for C.Fn2 'Set shutter speed range'.
