* To prevent damage or malfunction, do not
bend the light-emitting section above 90
degrees.
* Bounce lighting is possible simply by turn-
ing the light-emitting section up toward
the ceiling. All other operations are identi-
cal to shooting with direct lighting. How-
ever, note that the brightness may drop to
about 25%, though this is variable depend-
ing on the color and material of the refl ect-
ing surface. It is therefore recommended to open up the aperture (to decrease
the f-number as much as possible). The surface used for bounce lighting should
be as white as possible and its refl ectivity as high as possible. Note that, in color
photography, if the refl ecting surface has a color, the colored refl ection will stain
the subject in that color.
Using the Wide Panel
The EF-20 has a "wide panel" attached to it.
The fl ash usually covers an area with a focal
length up to 32 mm, and the wide panel is for
use when the lens in use is a wide-angle lens
with a shorter focal length. Specifi cally, the
wide panel makes the fl ash compatible with
a focal length up to 24 mm.
Operation is easy. All that is needed is fl ip up
the white panel on the lightemitting section
with a fi ngertip and place it on the lens of the
light-emitting section.
Note that the use of the guide panel decreas-
es the guide number to 14.
Important Note on Successive Firing
To prevent degradation due to overheating that may result from successive fi ring,
it is recommended to pause fi ring for more than 10 minutes after successive fi ring.

Initial Number of Flashes and Recycling Time
"AA"-size alkaline batteries x 2
"AA"-size NiMH batteries x 2
● Number of fl ashes: Measured under normal temperature, with new batteries that are within 3
months from their date of production, fl ashed every 30 seconds successively and recycled to the
point at which the READY lamp takes 30 seconds to come on after the last fl ash.
● Recycling time: The minimum time taken to activate the READY lamp after fi ring under the above
conditions.
