Compatible external flashes

Be sure to check the following items before using a commercial external flash.
(1) Exposures when using an external flash require that adjustments are made on the external
flash. If an external flash is used in auto mode, use a flash that can be adjusted to match the
f-number and ISO sensitivity settings on the camera.
(2) Even if the auto f-number and ISO sensitivity settings on the external flash correspond with
those 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 value on the external flash or
calculate the distance in manual mode.
(3) Use an external flash with an illumination angle that covers the angle of view of the lens.
However, when shooting at short range in wide mode, the bottom of the screen may be cut
off. It is advisable to use an external flash equipped with a wide adapter that provides broad
light distribution.
(4) Use an external flash with a flash time at full emission of 1/200 seconds or less. If the flash
time is longer, not all the light may contribute to exposure.
(5) Use of an external flash unit with communication capability or its accessory, other than
the Olympus FL series, may not only impair normal functioning, but may also cause
malfunction.
