Flash shooting
You cannot use the camera to adjust the amount of light emitted from a commercially
available flash except for a flash specified for use with this camera. To use a commercially
available flash, connect it to the hot shoe. Set the camera’s shooting mode to M.
1
Remove the hot shoe cover to connect the flash unit to the camera.
2
Set the shooting mode to M, then set the aperture value and shutter speed.
• Set the shutter speed to 1/180 sec. or slower. If the shutter speed is faster than this,
commercially available flashes cannot be used.
• A slower shutter speed may produce blurred images.
3
Turn on the flash.
• Be sure to turn on the flash after attaching the flash unit to the camera.
4
Set the ISO sensitivity and aperture value on the camera to match the flash control
mode on the flash.
• Refer to the flash’s manual for instructions on how to set its flash control mode.

Notes
• The flash fires each time the shutter is released. When you do not need to use the flash, turn
off the flash’s power.
• Check beforehand that the flash you are using is synchronized with the camera.
Non-specified commercial flashes
1) Exposures when using a flash require that adjustments be made on the flash. If a flash is
used in the auto mode, match it with the f-number and ISO sensitivity settings on the
camera.
2) Even if the flash auto f-number and ISO sensitivity are set the same as on the camera, the
correct exposure may not be obtained depending on the shooting conditions. In such a
case, adjust the auto f-number or ISO on the flash or calculate the distance in the manual
mode.
3) Use a flash with an illumination angle that matches the focal length of the lens. The focal
length of the lens for 35 mm film is approximately twice as long as the focal length of the
lenses designed for this camera.
4) Do not use a flash unit or other accessory TTL flash that has additional communication
functions other than the specified flashes, since it may not only fail to function normally,
but may also cause damage to the camera’s circuitry.
