Overview: The Fujifilm EF-42 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-42 can be used for direct flash (0°), pointed
upward for bounce lighting off a ceiling, and even rotated left or right for
bounce lighting off a wall. 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°. It can be
rotated left up to 180° (with stops at 30°, 60°, 90, 120°, and 150°), and
rotated right up to 120° (with stops at 30°, 60°, 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 wide panel, located above the
flash window, should be
used to diffuse the light to a wider area. The wide panel makes the
flash compatible with a focal length of up to 20mm.
TTL Flash Photography: TTL (Through-the-Lens) flash control
automatically adjusts flash output for optimal brightness. The flash also
responds to changes in camera settings, allowing the flash to be used at shutter
speeds slower than the flash sync speed.
Manual Flash Photography: Manual flash control is unaffected
by reflections, making it ideal for pictures of highly reflective or
unreflective subjects. You can make adjustments using the LCD panel.
Adjustable Flash Output: You can manually adjust the output
level of the flash as follows: Full (1/1), 1/2, 1/4, 1/8, 1/16, 1/32, or 1/64.
Exposure Compensation: You can manually adjust the exposure
compensation in 7 steps from -1.5 EV to +1.5 EV.
Controls and Indicators: The EF-42 has the following controls and
- LCD Panel: The LCD panel can indicate numerous modes
including focal length format (35mm or Digital), Exposure Compensation
(Positive or Negative) values, Zoom mode (Auto or Manual), and Power Ratio.
It also has an integrated flash range indicator scale. You can use the Mode
button to select the setting to adjust and the Select button to choose the
- Test/Charge Lamp: The Test/Charge lamp lights steadily whenever the flash is
ready to fire. Pressing the lamp activates a test firing.
Auto Power Off: If no operations are performed
for 15 minutes while the flash is on, the displays will turn off and the
flash is disabled. Pressing the camera's shutter button halfway or turning
the flash on and off will restore the flash's normal operations.
Power Requirements: The EF-42 is powered by 4 "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
|4 "AA" Alkaline batteries
||Approx. 3.5 seconds
|4 "AA" NiMH batteries
||Approx. 3 seconds
