Setting the Image-Recording Quality One-touch Image Quality Setting Custom Controls let you assign image-recording quality to the button, Multi-function button 2, or depth-of-field preview button with [One-touch image quality setting], so that you can temporarily switch image quality settings at the touch of a button before shooting. For details, see Custom Controls (p.337). If [51: Record func+card/folder sel.] is set to [Rec. separately], you cannot switch to the One-touch image quality setting. Maximum Burst During Continuous Shooting The number of shots for the maximum burst is displayed on the right in the viewfinder. If the maximum burst for continuous shooting is 99 or higher, "99" will be displayed. The maximum burst is displayed even when a card is not inserted in the camera. Make sure that a card is inserted before taking a picture. If the viewfinder displays "99" for the maximum burst, it means the maximum burst is 99 or higher. If the maximum burst decreases to 98 or lower and the internal buffer memory becomes full, "buSY" will be displayed in the viewfinder and on the top LCD panel. Shooting will then be disabled temporarily. If you stop continuous shooting, the maximum burst will increase. After all the captured images are written to the card, the maximum burst will be as listed on page 124. The maximum burst indicator in the viewfinder will not change even when you use a UDMA CF card. However, the maximum burst shown in parentheses on page 124 will apply. 126
