Shutter Speed Display
The shutter speeds from "D" to "R" indicate the denominator of the
fractional shutter speed. For example, "S" indicates 1/125 sec. Also, "H"
indicates 0.7 sec, and "J" indicates 15 sec.
• If the maximum aperture value blinks, it indicates
underexposure. Turn the <l> dial to set a slower
shutter speed until the blinking stops.
• If the minimum aperture value blinks, it indicates
overexposure. Turn the <l> dial to set a faster
shutter speed until the blinking stops.
