Choosing Aperture (A Aperture-Priority Mode) - Olympus E-PM2 Instruction Manual

Choosing aperture (A aperture-priority mode)

In mode A, you choose the aperture and let the camera automatically adjust shutter
speed for optimal exposure. Select A as the shooting mode.
• After pressing the F button (F), use FG to
choose the aperture.
• Larger apertures (lower F-numbers) decrease
depth of fi eld (the area in front of or behind the
focus point that appears to be in focus), softening
background details. Smaller apertures (higher
F-numbers) increase depth of fi eld.
