Other brands of extension flash that can be used.
When selecting an extension flash, use products which meet the
following basic conditions.
(1) Exposures when using an extension flash require that adjustments
be made on the extension flash unit.
If an extension flash is used in the Auto mode, matched it with the F
value and ISO sensitivity settings on the camera.
(2) Even if the auto F value and ISO sensitivity of the extension flash are
set to the same conditions as those on the camera, depending on the
photographic conditions, it is possible that the correct exposure may
not be obtained anyway. In such a case, adjust the auto F value or
ISO value on extension flash unit or calculate the distance in the
manual mode and use it that way. However, generally, the auto F
value and ISO value can only be adjusted 1 step and beyond that,
exposure compensation cannot be made. (Exposure compensation in
the camera is made invalid in extension flash photography.)
(3) Use a flash which is capable of covering an illumination angle for a
35 mm or larger lens when calculated for 32 mm film. However, in
close-up photography with the lens on the wide setting, the bottom of
the image may not expose correctly. The ideal is to have a wide
angle adapter to fit on the flash and spread the illumination angle so
it is wider.
(4) Use a flash unit with a flash time of 1/200 sec. or less when using the
flash at full strength. For devices with a long flash time, such as a
ring flash, a portion of the light emitted will not contribute to the
exposure.
(5) If a flash unit or other accessory with additional communications
functions other than the FL-40 is used, it may not only fail to function
normally, but may also cause damage to the camera’s circuitry. Do
not use such a device.
