New firmware has been released for the Canon EOS R3 and EOS R5. The updates are not very significant and are not immediately necessary for everyone. Check the changes to find out whether they are relevant to you.

Firmware version 1.7.1 has been released for the Canon EOS R3. With this firmware update, the Canon EOS R5 is now on version 2.0.0.

The changes for both models allow you to use the new Power Zoom adapters, and to store files of up to 2 terabytes on a CF-Express card.

There are also security improvements for FTPS connections on the EOS R3, as well as corrections for a number of rare error messages. View the list on Canon's website on the relevant firmware pages.

    Too bad no extra functionality is being added, such as that pre-shooting option (like on the R6ii).
    I think more people could benefit from that than from that High resolution shot/IBIS capture (1.8.1). Everyone will have tried that once, I assume, but perhaps that was as far as it went...

    I agree with that. Unfortunately, that won't happen. After all, the EOS 5D mark II is on its way.
