Overview: The Sigma EF-610 DG Super is a powerful flash with
lots of features that you don't get with the camera's built-in flash. It is
designed to work with the latest TTL auto-exposure systems of all the most
popular digital and film SLR cameras. The head can tilt up and swivel in both
directions, so you can bounce the flash in any direction. The flash is
compatible with Canon DSLR and E-TTL-compatible PowerShot cameras.
Shoe Mount: The Sigma EF-610 DG Super flash mounts to the
hot shoe on the
top of your compatible Canon camera. Flash trigger, exposure
setting, and focal length (zoom) setting are transferred to the flash via the
Flash Stand: The flash comes with a stand for placing the
unit in the desired position during slave flash, or for storing when
not in use. The stand has a threaded screw hole for placing on a tripod.
The firing direction of the flash is adjustable. The vertical angle ranges from
0° (straight forward) to 90° (straight up) with stops at 60° and 75°. You can
also tilt the head downward to 7° for close-up photography. The horizontal angle is 90° to the
right (stops at 60° and 75°) and 180° to the left (stops at 60°, 75°, 90°, 120°,
and 150°) for a total range of 270°.
Zoom Function: Generally, in the ETTL mode, the flash will
automatically set the zoom position according to the focal length of the lens.
Each time you press the Zoom button, the LCD panel display will change and
indicate the zoom position in sequence: 24mm, 28mm, 35mm, 50mm, 70mm, 85mm,
105mm, Auto. When the built-in wide panel
on the flash is engaged, the coverage will cover the angle of ultra wide-angle lenses
as short as 17 mm.
Wireless Flash: The Sigma EF-610 DG Super flash can be used
in the Wireless Flash mode, either as a master or slave flash unit. This allows
you to obtain the desired lighting effects even if the flash is located away
from the camera.
Modeling Flash: The Modeling Flash function lets you check
for intense reflections and shadows before taking the photograph. This is only
available for cameras that have the Modeling Flash function.
Catch Light Panel: The flash is equipped with a built-in
catch light panel, which can create a sparkle in the eyes of the subject when
the bounce flash mode is activated. The catch light panel is a white plastic
panel that extends over the flash head. A catch light is most effective when the
flash head is tilted upward at 90 degrees and pictures are taken at a close
Manual Flash: You can set the
flash output to Manual H or Manual L allowing you to set the flash power from
full to 1/128 in 1-step increments.
Rear-curtain Synchro: When photographing a moving subject,
the Rear-curtain Synchro mode allows the flash to be triggered immediately
before the rear-curtain of the shutter closes. Unlike front-curtain synchro,
this mode records blurred trails behind a moving subject, rather than in front,
for a more natural expression of motion.
AF Auxiliary Light: The EF-610 DG Super features an AF
Auxiliary Light to assist the camera's AutoFocus in low-light conditions.
Continuous Shooting Limitations: To prevent the flash from
overheating, you should discontinue using the flash for at least 10 minutes
after continuously firing the flash for the number of exposures below:
- TTL, M (1/1, 1/2): 20 continuous flash shots
- M (1/4, 1/8): 25 continuous flash shots
- M (1/16-1/32): 40 continuous flash shots
- Multi: 10 cycles
Batteries: The Sigma EF-610 DG Super flash uses
4 AA batteries. Alkaline, Nickel-Cadmium (NiCd) rechargeable, or Nickel Metal Hydride (Ni-MH)
rechargeable batteries are
recommended. Recycling time is approximately 7 seconds with alkaline batteries,
and approximately 5 seconds with NiCd or Ni-MH batteries. The number of flashes
are approximately 120 with alkaline, and approximately 160 with NiCd or Ni-MH.
Auto Power Off: To save battery power, the power will turn
off automatically after about 90 seconds of idle use.
Case: The included case houses and protects the Sigma EF-610
DG Super flash. There is also a small pocket inside the
case, where you can store the included flash stand. The case has a flap with a
