Our take on the Canon Speedlite 430EX

Experienced photographers know that perfect lighting is essential to getting the perfect shot. Canon's Speedlite 430EX provides the versatility and power to achieve more professional-looking flash photography with compatible Canon cameras, including all EOS SLR and select PowerShot models.

Simple to use, yet sophisticated, this flash's fully automatic "Evaluative Through-The-Lens" (E-TTL) exposure control works together with your Canon camera to provide the right illumination for your photos every time. All of the necessary connections are made by mounting the flash to your camera's accessory shoe. A manual mode with adjustable power settings has also been included to provide maximum flexibility and creative control. Plus, an informative LCD panel lets you quickly confirm your flash settings for accurate shooting.

The 430EX's flash head can be tilted and swiveled to place just the right amount of light where you want it. Bounced from walls or ceilings, reflected light can provide softer illumination with less glare and fewer shadows. And the powerful 430EX puts more light at your disposal, too. Take shots from far greater distances in low-light than your camera's built-in flash will allow.

The 430EX can also be used off-camera as part of a wireless multiple-flash photography system. Using Canon's Speedlite 580EX as the "master" unit, unlimited numbers of 430EX's can be trigged wirelessly to create dramatic lighting effects.

Note: For use only with compatible Canon cameras. Requires 4 "AA" batteries (not included).

Great flash

Sandy from Tennessee on 10/31/2007

I purchased this flash to use during an anniversary party. It worked flawlessly and since then I have used it for all my indoor photos, and some outdoor as well. This is a HUGE improvement over the built-in flash and can be positioned to get just the right effect you are looking for. This is my first "real" flash and I am very pleased with the results!




Hands-on research

Product Research



Compatibility: The Speedlite 430EX is compatible with all Canon EOS cameras including the Digital Rebel, EOS Digital Rebel XT and XTi, and the EOS 20D. It can also be used with the Canon PowerShot Pro 1, G2, G3, G5, and the PowerShot G6.

LCD: The LCD shows information on the flash's status. This includes (but is not limited to) flash range, zoom focal length, manual output level, multi flash settings, high speed sync, auto zoom for image size, and flash exposure compensation.

Shoe Mount: The 430EX flash mounts to the intelligent shoe on the top of the camera. Flash trigger, exposure setting, and focal length (zoom) setting are transferred to the flash via the intelligent shoe.

Variable angle: The firing direction of the flash is adjustable. The vertical angle ranges from 0° (straight forward) to 90° (straight up). The horizontal angle is 90° to the right and 180° to the left for a total range of 270°.

SE (Save Energy) Mode: If the flash isn't used (or adjusted) for 90 seconds the power is automatically turned off. If in wireless "slave" mode the power is turned off after 60 minutes.

Pilot Lamp/Button: The pilot lamp/button lights when the flash is ready to fire, green when ready for quick flash, red when ready for full flash. Depressing the lamp/button fires a test 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.

Flash Exposure Compensation: You can adjust the flash output as easily as normal exposure compensation. Can be set up to +/- 3 stops in either 1/2 or 1/3  stop increments. Note: If flash exposure compensation has been set with both the Speedlite and the camera, the Speedlite's flash exposure amount will override the camera's.

FE (Flash Exposure) Lock: This lock enables you to lock the correct flash exposure for any part of the picture.

High Speed Sync: You can use the flash with all shutter speeds. This is convenient when you want to use aperture priority for fill-flash portraits.

Second-Curtain Sync: With a slow shutter speed, you can create a light trail following the subject. The flash fires right before the shutter closes.

Bounce Flash: 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 Coverage: The flash coverage can be set to match the lens focal length from 24 mm to 105 mm (0.95" to 4.14"). It can be set automatically or manually. With the built-in wide panel on the 430EX flash, the coverage will be compatible with ultra wide-angle lenses as short as 14 mm (0.551").

Manual Flash: You can set the flash output from 1/64 power to 1/1 full power in full-stop increments.

AF-Assist Beam: Under low-light or low-contrast conditions, the built-in AF-assist beam will fire automatically to help the camera focus. The AF-Assist beam is effective from 2.3 - 32.8 ft (0.7cm - 10 m).

Wireless Selector Setting: The wireless selector is for switching between normal flash shooting and wireless flash shooting. Your choices are: off or slave. In the slave mode, the Speedlite 430EX flash can be used as a remote flash, and in conjunction with other flashes to give you various lighting effects.

Batteries: The 430EX flash uses 4 AA batteries. Alkaline, lithium, or nickel metal hydride (rechargeable) are recommended. Canon's testing with alkaline batteries yields a recycle time of 0.1 - 3.7 seconds and a flash count of 200 - 1400 (depending on flash settings).

Custom Functions: You can customize the Speedlite features to suit your  preferences. You have Six flash custom functions built into the 430EX (set on rear LCD panel).

Case: The padded case houses and protects the Speedlite 430EX flash. There is also a small pocket inside the case, where you can store the stand for the 430EX. The case has a flap lined with a Velcro strip to secure the flash in place.
