When the shutter speed is set at 1/100 sec (flicker-free mode), flickering is eliminated. • When looking at the picture on the monitor while the electronic shutter is being used, the object movement appears to be discontinuous. For example: in shutter speed of 1/2000 sec. Since the image for 1/2000 sec is taken out every 1/60 sec, this phenomenon occurs. • When high-speed shutter is used, light may not be sufficient. 12
