Compatibility: The Speedlite 320EX is compatible with all Canon EOS cameras and PowerShot G-series
Shoe Mount: The 320EX flash mounts to the intelligent shoe on the
top of your compatible Canon EOS or PowerShot G-series camera. Flash trigger, exposure
setting, and focal length (zoom) setting are transferred to the flash via the
LED Light: In addition to the flash, the 320EX has a
built-in LED light that can be used to illuminate nearby subjects in dim light.
The LED light can be used for shooting video, as a modeling light, or as an AF
assist beam. The LED will provide 3.5 to 4 hours of continuous lighting with
The firing direction of the flash is adjustable vertically and
horizontally. The vertical angle can be
0° (straight forward) to 90° (straight up) with additional settings at 60° and
75°. Horizontally, you can rotate the flash head to the left from 0° to 180°
(90° to the right) with additional settings at 60°, 75°, 90°, 120°, and 150°. By pointing the
flash head toward a wall or ceiling, the flash will bounce off the surface
before illuminating the subject. This can soften shadows behind the subject for
a more natural-looking shot.
Flash-ready Lamp: The Flash-ready
lamp lights when the flash is ready to fire. If the lamp is flashing, it is
ready for a quick flash, but the output will be 1/2 to 1/3 the normal flash.
Fully Automatic Flash Shooting:
When you set the camera's shooting mode to program AE or full auto, E-TTL
II/E-TTL fully automatic flash will make it as easy as normal AE shooting.
Camera Flash Control: When the 320EX is mounted to an EOS
digital camera with external flash control, you can control the following
functions with the camera:
- Flash Firing: You can enable or disable the flash. When disabled,
you can still use the flash as an AF-assist beam.
- Flash Mode: You can set the flash for E-TTL II (automatic) or
- E-TTL II: You can select the following metering types:
- Evaluative: fully automatic flash shooting from dark scenes
- Average: metering averaged to the entire scene
- Manual Flash Output: You can set the flash output from
1/1 (full power) to 1/64 power in 1/3-stop increments. (You can get metered
manual flash output with a Canon EOS 1D camera.)
- Shutter Sync: The flash can be set to the following sync types:
- 1st Curtain: Normal flash--flash fires when the shutter is
- 2nd Curtain: Flash fires right before the shutter closes
- High-Speed: Enables flash shooting at all shutter speeds,
effective when you want to use Aperture Priority for fill-flash
- Flash Exposure Compensation: You can adjust the flash output
level in the same way as normal exposure compensation.
Flash Coverage: The flash
coverage can be set to match the focal length of an EF lens from 24mm to 50mm
and an EF-S lens from 15mm to 32mm. With the flash head in normal position,
the coverage is set for an EF lens. You can change the flash coverage to that of
an EF-S lens by pulling the flash head forward.
Wireless Flash: To perform wireless flash shooting, the
camera or the Speedlight attached to the camera must have a master function. The
320EX fires as a slave flash when controlled from a master unit. The flash
comes with a stand that allows you to place the flash on a tabletop or a tripod.
The wireless slave function supports three groups and four channels.
Wireless Remote Control Flash: The flash can be used for
remote control shooting with cameras compatible with Remote Controller RC-1,
RC-5, or RC-6.
Batteries: The 320EX flash uses
4 AA batteries. Alkaline, lithium, or NiMH (Nickel-Metal Hydride) rechargeable
recommended. Canon's testing with alkaline batteries yields a recycle time of
0.1 - 2.3 seconds and a flash count of 180 - 1000 (depending on flash settings).
The LED light will light for approximately 3.5 hours with fully charged
Auto Power Off: To save battery power, the power will turn off
automatically after approximately 90 seconds
of idle use. To turn the Speedlite back on again, press your camera's shutter
button halfway down.
Carrying Case: The 320EX includes a soft carrying case with
a pocket for the mini stand.
