# Peripheral Illumination Correction

Depending on the characteristics of the lens used, the image around the corners of the picture may seem darker 
due to light fall-off or peripheral illumination drop. If the camcorder has correction data available for the EF lens 
used, it can apply this correction data to compensate as necessary.

1 Attach the lens you want to use.

2 Open the peripheral illumination correction screen.

[~ Camera Setup] > [Periph. Illum. Corr.]

• If correction data is available, the lens model name will appear on the 

screen. 

• If correction data is not available, [Periph. Illum. Corr.] will appear 

grayed out. Visit your local Canon Web site and check if there is 
correction data available for the lens you are using. If so, download the necessary update package and 
upgrade the camcorder’s firmware following the instructions supplied therein.

3  Select [On] and then press SET.

• As  long  as  [~ Camera Setup] > [Periph. Illum. Corr.] is set to [On], the camcorder will automatically apply 

the appropriate correction data.

NOTES

- The camcorder contains a register of correction data for compatible lenses that were available at the time 

the camcorder went on sale. Correction data for future lenses will be made available as part of the regular 
updates released for the camcorder’s firmware. For more details, visit your local Canon Web site.

- 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.

Changing a Lens While Maintaining the Time Code’s Progress

If you set an assignable button to [LENS EXCHANGE] (A 111), you can press 
the button to change the lens while the camcorder is turned on and the time 
code is running.

1 Set an assignable button to [LENS EXCHANGE] (A 111).

2 Press and hold the assignable button for 1 second.

• The camcorder enters lens exchange mode and the tally lamp will flash 

twice every 2 seconds. During this time, the time code will continue 
running.

• While the camcorder is in lens exchange mode, only the Q switch 

and the selected assignable button can be operated. Also, the LCD screen will turn off and output from 
the video terminals will be put on hold.

3 Remove the lens attached to the camcorder and attach the new lens.

• Do not set the Q switch to OFF.

4 Press the assignable button again.

• The camcorder exits lens exchange mode.

• Opening a CF card slot cover or removing the SD card will also cause the camcorder to exit lens 

exchange mode.
