* The file size, possible shots, and maximum burst are based on Canon's testing
standards (3:2 aspect ratio, ISO 100 and Standard Picture Style) using an 8 GB
card. These figures will vary depending on the subject, card brand, aspect
ratio, ISO speed, Picture Style, Custom Functions, and other settings.
* Figures in parentheses for the maximum burst apply to <o> high-speed
continuous shooting. Figures in parentheses apply to an UHS-I class 16 GB
card based on Canon's testing standards.
"Full" indicates that shooting is possible until the card becomes full with the

listed conditions.
Even if you use a UHS-I class card, the maximum burst indicator will not
change. The maximum burst in parentheses in the table will apply instead.
