Thank you for purchasing a Canon product.
The Canon Speedlite 270EX II is a compact flash unit for Canon EOS cameras, and works
with
theE-TTL II and E-TTL autoflash systems. All control is performed on the camera side,
letting
you easily enjoy flash shooting in the same manner as a built-in flash.
• Use
with an EOS DIGITAL camera
• The 270EX
II is designed for optimum use with an EOS DIGITAL camera.
• Use
with an EOS film camera
• When used with
an E-TTL II orE-TTL autoflash EOS film camera, autoflash shooting can
be performed in the same manner as when used with an EOS DIGITAL camera.
• The 270EX
II cannot be used with TTL autoflash EOS film cameras.
• Be
sure to also read the description of flash shooting in the camera's instruction
manual. For convenience, a camera compatible with E- TTL 11/E- TTL autoflash systems is
indicated as Type-A camera in camera's instruction manuals.

Installing the Batteries
Slide the battery compartment cover
and open it as shown by the arrows.
Install two batteries.
4P Make sure the+ and- battery contacts are correctly
oriented.
® Return the cover to its original position.
Recycling Time and Flash Count
Recycling Time: Approx. 0.1 -3.9 sec.
Flash Count: Approx. 100 -680 flashes
~ Based on new size-AA/LR6 alkaline batteries and Canon's testing standards. 5

0 •
Be sure to use a new set
of
two batteries
of
the same brand. When replacing the
batteries, replace both batteries at once.
~
Do not fire more than 20 continuous flashes
in
a short time.
If you fire more than 20 continuous flashes
in
a short time, the overheating prevention
function may be activated and make the recycling time about 8 to 20 sec. Ifthis occurs,
allow a rest time of about 15 min. and the functioning
of
the flash will then return to
normal.
•
If
you change the batteries after firing flashes continuously, be aware that the batteries
might be hot.
• Using size-AA/LR6 batteries other than the alkaline type may cause improper battery
contact due to the irregular shape
of
the battery contacts.
[lJ
Size-AAILR6 Ni-MH or lithium batteries can also be used.

Attaching the Flash
Be sure to turn off the Speedlite before attaching or detaching
it.

Flash Shooting
in
Each Camera Mode
Tv:
Shutter Priority AE
In
this mode, the camera will automatically adjust the flash output level to achieve standard
exposure for the automatically set aperture.
• Ifthe aperture display blinks, it means that the background exposure will be underexposed
or overexposed. Adjust the shutter speed until the aperture display stops blinking.
Av:
Aperture Priority AE
In
this mode, the camera will automatically adjust the flash output level to achieve standard
exposure for the set aperture.
Ifthe background
is
dark, like a night scene, a slow sync speed will be used to obtain a
standard exposure
of
both the main subject and background. Standard exposure ofthe main
subject
is
obtained with the flash, while a standard exposure ofthe background
is
obtained
with a slow shutter speed.
• Since a slow shutter speed will be used for low-light scenes, using a tripod
is
recommended.
• If the shutter speed display blinks, it means that the background exposure will be
underexposed or overexposed. Adjust the aperture until the shutter speed display stops
blinking.
9

M:
Manual Exposure
Select this mode
if
you want to set both the shutter speed and aperture manually.
As the camera will automatically adjust the flash output level according to the aperture you
set, the exposure
of
the main subject will be standard. The exposure
of
the background is
obtained with the shutter speed and aperture combination you set.

Switching Flash Coverage
• Flash head (normal position)
• Flash head (pulled forward)
The Guide No. is 22/72 (ISO 100
in
meters/feet). The
maximum flash coverage matches an EF 28mm wide
angle lens (EF-S 18mm).
The Guide No. is 27/89 (ISO 100
in
meters/feet). The flash
coverage matches an EF 50mm (EF-S 32mm) or lenses
with longer focal length.
0
When
shooting
with
a lens wider
than
EF
50mm
(EF-S
32mm), the periphery of
the
picture may become dark.
[]]
See
p.26
for guidelines about the flash shooting range.
11

Bounce Flash Shooting
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 more natural-
looking shots.
~
Pull the flash head forward and
then tilt it upward to determine
the flash head angle.
0 • When the resulting picture
is
dark, set a smaller F
number (open the aperture) or increase the ISO
speed and try shooting again. The resulting
picture may also
be
dark ifthe wall or ceiling
is
too
far
away.
e The wall or ceiling should
be
plain white or nearly
white for high reflectance. Ifthe bounce surface
is
colored, this may produce a color cast
in
the
resulting picture.
e
After shooting with bounce flash, be sure to
return the flash head to the forward-facing
position and push the flash head back into its
original position.
[i}
Determine the best angle for bounce flash
by
taking test shots and checking the resulting
pictures
on
the
camera LCD monitor.

Other Functions
Auto Power Off
To
save battery power, power will be turned
off
automatically after 90 sec.
of
idle use. Press
the camera's shutter button to turn on the Speedlite again.
* Canceling the auto power
off
function is possible. (p.16)
AF-Assist Beam
When you press the camera's shutter button halfway, the flash may fire repeatedly. This is
the AF-assist beam function that facilitates autofocus for dark scenes. Its effective range is
approximately 4 m/13.1
ft.
This function is available when using the Speedlite with an EOS DIGITAL camera that has an
external flash control function. Depending on the camera model, note that the firmware
may
need to be updated.
Modeling Flash
Pressing the camera's depth-of-field button will fire the flash continuously for 1 sec. This
enables you to see the shadow effects on the subject before flash shooting.
0
Do
not fire the modeling flash more than 1
0 consecutive times. If
you
fire the modeling flash
10
consecutive times, allow the Speedlite
to
rest for at least
10
min.
to
avoid overheating
and
deteriorating
the
flash head.

in
slave mode, the power turns off if no operations
are made within 60 or 10 minutes.
C.Fn-11: Slave auto power off cancel (Within 8 hours*/Within 1 hour)
When the master unit has a function to cancel the auto power off
on
the slave

Wireless Flash Shooting
To
perform wireless flash shooting, the camera or the Speedlite attached to the camera must
have a master function. The 270EX
II
fires as a slave flash when controlled from a master
unit. For the detailed shooting method, refer to the instruction manual of the camera or the
Speedlite with a master function.1
l
Set the camera or Speedlite
as
the
master unit.
Set the 270EX
II
as the slave unit.
• Set the power switch of the 270EX
II
to
<SLAVE>.
3 Attach the 270EX
II
to the supplied
mini stand and position the flash.
• Indoors, you can perform wireless flash shooting
using the reflection of the surrounding walls without
having to point the wireless sensor
of
the 270EX
II
toward the camera. Position the 270EX
II
while
checking that it can fire.
17

Transmission channel
You can use the flash regardless
of
the transmission channel
(1
to 4)
on
the master unit.
Slave ID (firing group)
The slave ID is set (fixed) to group
A.
This cannot be changed to group B or
C.
Auto power off on the slave unit
When the power switch
of
the 270EX
II
is
set to
<SLAVE>,
the power of the flash turns off
automatically if no operations are made within 60 or 10 minutes (p.16 C.Fn-10).
Ifthe master unit does not have a function for canceling the auto power off (p.16 C.Fn-11) on
the 270EX
II,
set the power switch of the 270EX
II
to
<OFF>
and then to
<SLAVE>
again.
0
The supplied
mini
stand
is
for
use
only with
the
270EX
II.
Use
with another flash
may
cause
the attached flash
to
fall.
18
Using the 270EX
II
for Remote Control Shooting
During Wireless Flash Shooting
The 270EX
II
can be used for remote control shooting with cameras compatible with Remote
Controller RC-1, RC-5, or RC-6. When wireless flash shooting
is
enabled, remote control
shooting
is
possible while changing easily the position
of
the 270EX
II.
