Preparing the Camera
38
• When peripheral illumination correction is activated:
- Depending on the recording conditions, noise may appear in the periphery of the image as a result of the
correction.
- The level of correction will be lower for lenses that cannot provide distance information.
- The level of correction will be lower the higher the ISO speed/gain setting used.
- Due to the difference in sensor size, when using EF-S lenses, peripheral illumination fall-off may be more
pronounced.
Updating the Firmware of an EF Lens
You can update the lens firmware of the EF lens attached to the camera. For details about firmware updates for
EF lenses, visit your local Canon Web site.
1 Download the lens firmware update file from the Canon Web site and
save it on an SD card. Insert the SD card containing the lens firmware
update into the SD card slot.
2 Attach the lens you wish to update to the camera and open the lens
firmware submenu.
[System Setup] > [Firmware] > [Lens]
• The current lens firmware version will appear on the screen.
• If the [Lens] option is grayed out, the attached lens may not support firmware updates or the SD card used
may not contain a valid lens firmware file. Check the lens and SD card and repeat the procedure from the
beginning.
3 Select [OK] and then press SET.
4 Select the lens firmware file (file extension .LFU) and then press SET.

• Be sure to observe the following precautions while the lens firmware is being updated.
- Do not disconnect the power source or turn off the camera.
- Do not remove the lens.

NOTES
