Shutter priority shooting The camera sets the optimum aperture value automatically for the shutter speed you have selected. Set the shutter speed depending on the type of effect you want. A higher shutter speed allows you to capture a fast-moving subject without blur, and a slower shutter speed blurs a moving subject, creating a feeling of speed or motion. A fast shutter speed can freeze a fast action scene without any blur. A slow shutter speed will blur a fast action scene. This blurring will give the impression of dynamic motion. Set the mode dial to S and turn the control dial to set the shutter speed. Aperture value Slower shutter speed Shutter speed AF confirmation mark Shooting mode 44 Viewfinder EN Faster shutter speed
