Figures for the file size, possible shots, and maximum burst during continuous
shooting are based on Canon's testing standards (ISO 100 and Standard
Picture Style) using a 4GB card. These figures will vary depending on the
subject, card brand, ISO speed, Picture Style, Custom Functions, etc.
The maximum burst applies to high-speed continuous shooting. Figures in
parentheses apply to an Ultra DMA (UDMA) 4GB card based on Canon's
testing standards.
If you select both RAW and JPEG, the same image will be recorded
simultaneously to the card in both types at the selected image-recording
quality. The two images will be saved in the same folder with the same
file numbers (file extension .JPG for JPEG and .CR2 for RAW).
The icons are read as follows: 1 (RAW), 41 (Medium RAW),
61 (Small RAW), JPEG, 7 (Fine), 8 (Normal), 3 (Large), 4
(Medium), and 6 (Small).
