Choosing Aperture (A Aperture-Priority Mode) - Olympus E-M10 Instruction Manual

Choosing aperture (A aperture-priority mode)

In mode A, you choose the aperture and let the camera automatically adjust shutter
speed for correct exposure. Rotate the mode dial to A and then use the rear dial to
select an aperture value.
• You can use the front dial to select exposure
compensation.
• 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.
