QuickGuide to Canon320EX Speedlite FeaturesThe purpose of this QuickGuide is to provide a concisereview of how to operate the basic features and functionsof the Canon 320EX Speedlite. Unless otherwise noted,the following instructions require your 320EX Speedlite tobe mounted to your camera’s hot shoe. This will allow yourcamera to communicate with the 320EX and for you tomake flash settings with the camera’s menu system.E-TTL II Auto Flash Set-upFor cameras with built-in flash:1. Press the camera Menu button.2. Select the first Shooting Menu (first camera icon on theleft).3. Select [Flash control] or [External Speedlite control].4. Select [External flash func. setting]. Press Set.5. Set [Flash mode] to [E-TTL II]This step is not necessary for cameras that have no built-inflash. It is also not necessary if you have not previouslychanged the default flash settings on your camera.Camera Exposure Mode SettingsThe 320EX will function in any of the camera exposuremodes listed below. The maximum shutter speed at whichyour camera can synchronize with the flash exposure isrepresented by “1/x sec” (such as 1/200th second on EOSRebel models).1 2 3Mode Shutter speed ApertureFull Auto, P,A-DEPSet automatically (1/x sec. – 1/60 sec.) AutomaticTV Set manually (1/x sec. – 30 sec.) AutomaticAV Set automatically (1/x sec. – 30 sec.) ManualM Set manually (1/x sec. – 30 sec., Bulb) ManualThe mode you choose will depend mainly on the balanceyou prefer between the flash exposure and ambientlight exposure. Longer shutter speeds will allow longerambient light exposures to help prevent dark backgrounds;however, long exposures also risk blur from subject orcamera motion. Smaller apertures provide more depth-of-field but require more flash power and reduce themaximum flash range.Flash CoverageThe flash head can be manually extended or retracted tobetter match the flash coverage to the camera and lens inuse. Refer to the table below for recommended settings.Camera type Flash Head Normal Head ExtendedAPS-C size sensor(Rebel series, 60D, 7D)15mm or longer lens 32mm or longerlensFull-frame sensor(EOS 5D & 1Ds series)24mm or longer lens 50mm or longerlensKey Features and Controls (front)Flash headRemote release buttonAllows remote triggering ofcameras compatible with theRC-1, RC-5, or RC-6 RemoteControllers*LED lightWireless sensorRemote control transmitter* EOS Digital Rebel; Rebel XT, XTi; Rebel XSi; Rebel T1i, T2i,T3i; EOS 7D, EOS 5D Mark II (as of mid-2011).E-TTL II Flash RangeThe flash range will vary depending on the ISO setting,angle of coverage, and maximum aperture of your lens. Ifyou see a blinking <> icon in your viewfinder then yoursubject is too far away. You should either move closer orincrease the ISO. The table on the reverse side providesa guide to minimum and maximum shooting ranges for theEF-S 18-55mm f/3.5-5.6 IS zoom. Do not use the 320EX inthe extended position at a focal length of 18mm or less, orthe edges of the frame will be darker than the center.Key Features and Controls (back)Firing group selection switch Assigns firinggroup when 320EX is combined with otherwireless SpeedlitesTELE lampGlows steadily when the flash coveragematches the lens coverage.
