All Canon EOS cameras have firmware inside that controls how they operate and perform. A firmware update is created when there’s an improvement in functionality, or a correction of problematic behaviours and errors.
What is a firmware update?
A firmware update is a software program that is possible to install in to a product like a DSLR camera. In most instances a firmware update is provided directly from the manufacturer of the camera. You can find some talented engineers creating their own firmware to run in another manufacturers hardware.
For Canon EOS cameras the firmware update can do many things to change the functions and operation of a camera, it cannot add functions that require changes in the camera hardware. So unlike the April Fools story I wrote, it would not be possible to activate an increased resolution in a camera if the sensor (hardware) doesn’t support it.

5-step guide to update your Canon EOS firmware
Canon firmware updates come in the form of a firmware image file with the extension .FIR. You can dowload a compressed file from Canon and expand it on your computer. Often there will be a PDF with specific instructions for your camera and firmware included in the compressed file along with the firmware.
- Format a small-sized card in the camera
- Remove any fitted lens or Speedlite from the camera, make sure the battery in the camera is fully charged
- Put the firmware file you have downloaded and uncompressed on the camera’s memory card (use either a card reader or EOS Utility)
- Switch on the camera and navigate to the Firmware menu item, and choose to update
- Don’t press any buttons on the camera, or switch it off during the update – you can kill the camera
Since the firmware files are not huge in size, then a small card of 2GB or less is worth keeping just to use for firmware updates.
