Firmware: Canon confirms January firmware release for RF 70-200mm f/2.8L IS USM fix

A couple of weeks ago it was reported that Canon would be releasing a firmware update to fix an autofocus issue with the brand new Canon RF 70-200mm f/2.8L IS USM when shooting at or near its minimum focusing distance.

Canon has now confirmed that the update/fix will come in January 2020.

It has been confirmed that when using the RF70-200mm F2.8 L 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.

Note: New firmware being released at this time is for lenses equipped with firmware version 1.0.5 or earlier. The lens firmware version can be checked in the camera’s menu.

Even Canon lets a mistake loose in the wild once in a while. Makes me feel better about one of my biggest, dumbest blunders. Happened just last week. About 25% of an Xmas program, shot on the EOS R (which was a companion, fortunately, to a 5DIV), inadvertently low-level formatted. DOH!!!

(In the meantime, I've set my cameras to NOT low-level format SD cards by default, and taken other idiot-proofing steps).

Sigh... Even Canon screws up now and then. After all, we are only human.

Looking forward to the firmware update AND some reviews confirming the problem has been solved! Intensely curious about this lens.

Yes, everyone makes mistakes. There are so many variables with complex devices, I'm not surprised these things happens. As for MFD, my experience is non-macro lenses tend to be weak used too close, but I'm sure that varies a lot.
