Overview: The Fujifilm EF-20 is a shoe mount flash unit for
use with Fujifilm cameras equipped with an accessory hot shoe, including the
FinePix X100 and FinePix HS20.
Bounce Flash: The EF-20 can be used for direct flash (0°) or pointed
upward for bounce lighting. Bounce flash can produce softer, more natural
shadows in your photographs than direct flash. The light-emitting section of the
flash can be aimed upward, with stops at 45°, 60°, 75°, and 90°.
Wide Panel: When using a wide-angle lens, the flash may not cover all
of the area being photographed. In this case, the flip-down wide panel should be
used to diffuse the light to a wider area. Without the wide panel, the flash
usually covers an area with a focal length up to 32mm. The wide panel makes the
flash compatible with a focal length of up to 24mm.
Controls and Indicators: The EF-20 has the following controls and
- Ready Lamp: The ready lamp lights steadily whenever the flash is
ready to fire. Pressing the ready lamp activates a test firing.
- EV Adjust: The EV Adjust lets you fine adjust the brightness
level of the flash. If the picture is too bright or too dark, you can adjust
the brightness in 5 steps from -1 EV to + 1 EV.
- TTL Effective Range: Using TTL (through the lens) flash exposure
control, the selected EV adjustment indicator lights for about 3 seconds
after the flash fires to indicate the subject is within the effective range.
Power Requirements: The EF-20 is powered by 2 "AA" batteries (not
included). You can use either alkaline, Lithium, or Nickel-Metal Hydride (NiMH)
rechargeable batteries. The number of flashes and recycling time for each
battery type is as follows:
| ||Number of Flashes|
|2 "AA" Alkaline batteries||Approx. 200||Approx. 5 seconds|
|2 "AA" NiMH batteries||Approx. 280||Approx. 4 seconds|
