Compatibility: The Speedlite 270EX II is compatible with all Canon EOS cameras and PowerShot G-series
Shoe Mount: The 270EX II 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
The firing direction of the flash is adjustable vertically by pulling
the flash head forward and tilting it backward. The vertical angle can be
0° (straight forward) to 90° (straight up) with additional settings at 60° and
75°. 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.
Pilot Lamp: The pilot
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 270EX II 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
- 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.
- 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
Flash Coverage: The flash
coverage can be set to match the focal length of an EF lens from 28mm to 50mm
and an EF-S lens from 17.5mm to 31.3mm. 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
270EX II 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.
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 270EX II flash uses
2 AA batteries. Alkaline, lithium, or NiMH (Nickel-Metal Hydride) rechargeable
recommended. Canon's testing with alkaline batteries yields a recycle time of
0.1 - 3.9 seconds and a flash count of 100 - 680 (depending on flash settings).
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.
