    Firmware Version 2.0.3 incorporates the following fix:

    Corrects a phenomenon in which when using the camera with the EF-S 18-135mm f/3.5-5.6 IS USM or EF 70-300mm f/4-5.6 IS II USM lens, even if lens aberration correction is set to "Enable", correction will not be applied.

    Firmware Version 2.0.3 is for cameras with firmware up to Version 2.0.2. If the camera's firmware is already Version 2.0.3, it is not necessary to update the firmware.

    When updating the firmware of the camera, please review the instructions thoroughly before you download the firmware.

    Preparations for a firmware update:

    After the downloaded compressed file (.zip file) is extracted, a firmware folder is created.

    *Extracting the downloaded file:
    Right-click the zip file, and then select Extract All to extract the file.

    The extracted folder contains the firmware (File name: EOSM1203.FIR, File size: 17,744,080 bytes) and instructions on the firmware update procedures (a PDF file in five languages: Japanese, English, French, Spanish, and Simplified Chinese).

    Before starting the firmware update operations, please confirm the contents of the download, and carefully read through the firmware update procedures.
