* Figures for the file size, number of possible shots, and maximum burst are based on Canon's 4GB test card and testing standards (3:2 aspect ratio, ISO 100, and Standard Picture Style). These figures will vary depending on the subject, card brand, aspect ratio, ISO speed, Picture Style, Custom Functions, and other settings.
Reference:
RAW + JPEG records a RAW and JPEG image with a single shot. The two images are saved to the card simultaneously. The two images will be saved in the same folder with the same file numbers (file extension .JPG for JPEG and .CR2 for RAW).

*1:Frame rate is the value that indicates the number of frames recorded per second (fps).
[ ][ ] :For areas where the TV format is NTSC (North America, Japan, Korea, Mexico, etc.).
[ ][ ] :For areas where the TV format is PAL (Europe, Russia, China, Australia, etc.).
[ ] :Mainly for motion pictures.
*2:It will give a telephoto effect of about 7x. This shooting mode is called Movie crop.
Note:
- Due to limitations of the file system, movie shooting will stop automatically if the file size of a single movie clip reaches 4GB. To resume movie shooting, press the <
> button. (A new movie file starts being recorded.)
- With ImageBrowser (provided software), you can extract still photos from a movie. The still image quality will be as follows: Approx. 2.1 megapixels at [1920x1080], approx. 920,000 pixels at [1280x720], and approx. 310,000 pixels at [640x480].
Important:
- When shooting movies, use a large-capacity SD card rated SD Speed Class 6 "
" or higher.
- If you use a slow-writing card when shooting movies, the movie might not be recorded properly. And if you playback a movie on a card having a slow reading speed, the movie might not playback properly.
- An increase of the camera's temperature may cause movie shooting to stop before the maximum recording time shown in the table above.
- The maximum recording time of one movie clip is 29 min. 59 sec. Depending on the subject and the increase in the camera's temperature, the movie shooting might stop sooner than 29 min. 59 sec.
