A (Programmed auto) Use for automatic control of the exposure by the camera. • Different combinations of shutter speed and aperture value can be selected without changing the exposure by rotating the main command dial ("flexible program"). While 1/125 F5.6 1280 flexible program is in effect, a flexible program mark (A) is displayed next to the mode indicator (A) in the upper left of the monitor. • To cancel flexible program, rotate the main command dial until the flexible program mark (A) is no longer displayed, or press the AE-L/AF-L button while pressing the w1 button. Selecting another shooting mode, or turning off the camera, also cancels flexible program. Shooting Features B (Shutter-priority auto) Use to shoot fast moving subjects at a fast shutter speed, or use to emphasize the movements of a moving subject at a slow shutter speed. • The shutter speed can be adjusted by rotating the main command dial. 1/125 F5.6 1280 C (Aperture-priority auto) Use to bring subjects including both the foreground and background into focus or blur the subject's background intentionally. • The aperture value can be adjusted by rotating the sub-command dial. 1/250 F5.6 1280 D (Manual) Use to control the exposure according to shooting requirements. • When adjusting the aperture value or shutter speed, the degree of deviation from the exposure value measured by the camera is displayed in the exposure indicator of the 1/125 F5.6 1280 monitor. The degree of deviation in the exposure indicator is displayed in EVs (-3 to Exposure indicator +3 EV in increments of 1/3 EV). • The shutter speed can be adjusted by rotating the main command dial and the aperture value can be adjusted by rotating the sub-command dial. 51
