    Canon has pulled firmware v1.2.0 for the Canon EOS R3 due to a bug

    Canon has removed the firmware v1.2.0 download for the Canon EOS R3 due to a bug in the software.

    The bug is described on the DPReview Forum

    The issue is that if you have v1.2 on your camera and then perform a reset the mode dial does not work correctly and you cannot change between Tv Av etc

    If you have updated to firmware v1.2.0 for the Canon EOS R3, do not do any resets until v1.2.1 is released.

    Canon has always fixed these sorts of firmware bugs pretty quickly, so I would expect an update very soon.

      Another example of why I wait a few weeks to install new computer OS updates and camera firmware updates.

      Good luck with that on Windows 11 (Mac people are more fortunate as I understand).

      Was just going to say the same thing. No sense in being the Guinea Pig for these experiments.

      Okay, my R3 is on its way back from CPS for a clean and check. I suspect they will updated the firmware. :) So, I wondering what does it mean to "perform a reset?"

      After they remove the function to shoot 50 frames at a195 fps in the update, maybe I can sell bootlegged copies of the firmware since to those who do not mind a few bugs in trade for insane fps.

      I guess it's the reset to factory settings ?

      OT: ICYMI, Canon released their quarterly financial reports on the 26th. They are still having parts supply problems. https://global.canon/en/ir/library/results.html

      A sensible approach, although some bugs slip through testing and are only found post-deployment as a result of end users doing their thing - but it's always better that someone else finds it before you!

      I guess I'll find out. I saved my settings to the card before sending the body in. I'll see what happens when I load the card.

      This is why I wait more than a month before applying a firmware.

      I take a wait and see approach when updating a camera that hasn’t been giving me any issues.

      I updated the R3 with FW 1.2, before being pulled, and didn't reset the cam. I usually switch between the custom saved modes and shoot. So far the mode dial and the rest of functions including Hc frame rate are ok.

      I'm thinking it means factory reset. But it is an interesting bug, I wonder why it only happens after the factory reset?

      And this folks is what happens when cameras become heavily dependent on computing, the increase in functionality comes at the cost of an increase in complexity. Along with this comes an increasing number of variables that are difficult to account for whenever changes and updates are made. Without a proper testing environment and time to carry out exhaustive tests, the consumers/end-users become the beta testers.

      Now just like your personal computer, cameras can have software (firmware) bugs, and they also freeze up and require power disconnection (battery removal) to get them running again. As more computing functionality gets added, expect much more of this. Anyone who has ever worked in the IT industry will tell you this is a immutable aspect of computing technology.

      As I always keep reminding people, there is always a cost for everything. The personal choice is if you're happy with the tradeoffs.

      they probably just need better programmers. Canon is a camera company i cant see the software being that complicated compared to cellphone tech. the issue seems like a simple fix.
