The Canon Speedlite 430ex ii flash unit replaces the Speedlite 430EX. Redesigned interface, improved speed. There is an updated version 3 on the market, featuring speed and a redesigned interface.


Canon Speedlite 430EX II. Overview

Canon Speedlite 430ex ii is a flash for Canon EOS cameras, guide number 43 (ISO100, 105mm). An updated version of the Canon Speedlite 430 EX with a metal shoe and a slightly faster reload speed. The rest, in principle, is unchanged: the same matrix display with green backlighting, remote control, custom C.fn settings from the camera and flash menus. Built-in autofocus light, diffuser.

Speedlite 430EX II Controls

The main controls are located on the rear panel (the panel facing the photographer when the flash is attached to the camera). Buttons, display, switches. It differs little from the Canon 430EX. The controls are sunk into the body on purpose so as not to knock off the settings during operation.

Swivel head

Has the ability to tilt horizontally and vertically for shooting with bounced light. There is a flash lamp in the head, the lamp has a limited resource. The swivel mechanism is activated by pressing the PUSH button on the head itself. A diffuser is integrated into the head to increase light diffusion. It helps a lot when you need to knock out the shadows of the subject.

It is pulled out of the body by a "pulling" movement. To improve reflectance and use it in reportage photography, many people wrap a piece of paper or a business card around the head of the flash. The result is a soft and diffused light (not always a "flash on the forehead" is permissible).

I often only needed to light up my subjects just a little in order to pick out the shadows. The built-in diffuser and a white business card help a lot in this work.


Matrix, has a green backlight. The backlight is activated by pressing the C.Fn (Custom Functions) button once and extinguishes after 12 seconds. The display shows the flash modes. Everything that is needed is printed on the display in advance (battery savings should be economical).

Buttons and switches

Let's go directly to the description of the panel buttons.

C.Fn in Canon Speedlite 430EX II

canon speedlite 430exii buttons 1

Pressing the C.Fn button once and the Canon 430ex ii turns on the flash display backlight. The backlight brightness is stable, but it seems to me that the brightness could be made less intense. A long press on the button activates the "additional functions" menu. Additional functions appear on the flash control screen in the camera menu. Decoding and setting can be done both on the flash and through the camera menu. Flash memorizes C.Fn in nonvolatile memory. List of additional functions:

  • C.Fn 0 - Distance units (0 - Meters, 1 - Feet)
  • C.Fn 1 - Auto Power Off (0 - Enabled, 1 - Disabled)
  • C.Fn 2 - Modeling flash (0 - DOF button, 1 - Flash test button, 2 - Both buttons, 3 - Disable)
  • C.Fn 7 - Test flash power (0 - 1 \ 32, 1 - Full)
  • C.Fn 8 - Turn on the AF assist lamp (0 - Yes, 1 - No)
  • C.Fn 9 - Auto adjust to sensor size (0 - Yes, 1 - No)
  • C.Fn 10 - Slave Flash Timer (0-60 minutes, 1-10 minutes)
  • C.Fn 11 - Slave flash auto off canceling (0 - Up to 8 hours, 1 - Up to 1 hour)
  • C.Fn 14 - Flash area / Aperture information (0 - Maximum distance, 1 - Aperture)

The rooms are out of order. Apparently reserved in the general system of additional functions for all Canon flash units.

Switching operation modes from automatic exposure metering to manual mode. The flash output can be adjusted.

Sync toggle button

Forcing the flash and camera to sync at high speeds shutter, switching synchronization to the second curtain mode.

The button allows you to manually set the guide number (the equivalent is displayed in the form of focal length). A long press activates the slave flash mode.

Pilot light. I use it to evaluate the cut-off of an object. When the flash is in hand, and the autofocus of the camera dulls in the dark, it can be used for additional illumination of the subject.

Power switch

Everything is simple here. Flash power on / off.

Shoe retainer

A device that is more convenient than the plastic retainer of the previous model. The latch is rotated and clamped by a button, blocking the flash in the camera shoe.

Battery compartment cover

Hides a nest underneath for AA elements.

Supported metering modes

  • TTL (exposure metering in real time by reflection from the film, TTL-OTF), Canon calls them "Type B Cameras" in the manual
  • E-TTL (estimated exposure metering using pre-flash) Canon calls them "Type A Cameras" in Canon's manual
  • E-TTL II (estimated exposure metering with pre-flash and focusing distance lens) Canon calls them "Type A Cameras" in the manual

Camera types A and B

Before Canon officially split its cameras into two Type A and Type B cameras, there were several variations of Type A.TTL flash control and modeling light modes supported in second generation Type A cameras. Third generation cameras also support E-TTL II.

Canon 430EX II operating modes

Key for me are the operating modes of the Canon Speedlite 430EX II.

canon speedlite 430exii 5

High speed sync

Allows the Speedlite 430EX II to be used in FP sync mode, at all speeds shutter... In this case, the flash output power is automatically adjusted. High-speed sync helps a lot when shooting on a sunny day, when a person or a group portrait needs to be shot so that the people in the photo turn out to be in a normal state, and not in a gloomy-squeezed state.

Second curtain sync

Allows for a variety of lighting techniques when the Speedlite 430EX II's subject is backlit just before closing shutter.

Depth of field preview

Activated by button DOFV on the camera. Allows you to assess depth of field and the location of shadows.

Focus Assist in Low Light Conditions

Helps the camera to hit the target using the infrared radiation of the Speedlite 430EX II sensors.

overheat protection

The Canon 430EX II has built-in overheating protection. When triggered more than 10 times in a row, the electronics limits the number of times the lamp is switched on to 1 time in 10-15 seconds. The user's manual warns you to protect the flash from long bursts. The flash circuit uses a rare (as I understand it, it was simply created under the order of Canon) IGBT-transistor, which overheats when working at an unbearable pace.

Flash Guide Number Adjustment

The Speedlite 430EX II adjusts the lamp power to the attached lens (24 to 105mm range).

Slave flash mode

For remote shooting without a synchronizer, a light trap is used. Optionally, through the camera menu, you can enable work as a pair or alone. The body of the Speedlite 430EX II should be turned towards the built-in flash of the camera, and in the settings of the device it is necessary to indicate “On” in the “External flash control” mode. To turn the Speedlite 430EX II into light trap mode, just long press the Zoom button.

Case and build quality

The plastic, moving parts have a noticeable backlash even on the new flash. The flash shoe is metal; on the front panel, under the red glass, the slave flash indicator, the radio transmitter window, and the autofocus lamp are hidden.

Canon 430EX beep while reloading. Canon 430EX II is silent like a partisan. "Sound confirmation of charge" made it possible by ear to determine the level of the remaining battery charge, because the graphic indicator of the display is not very informative.

The Canon 430EX II is designed to use rechargeable AA batteries or batteries. 4 AA batteries with a capacity of 2500mAh are enough for about 300 operations. If you expect to use more time, it is better to carry spare batteries with you.

The Canon 430EX II benefits

  • Accurate exposure and no overexposure.
  • High-speed sync. If this function is not available, the flash will operate normally when excerptx up to 1 \ 200 (in general, depends on shutter camera) seconds.
  • Slave flash support

Disadvantages of the Canon 430EX II

  • The Canon 430EX II is criticized by the backlash of the upper rotary part (more than 3 mm). The shoe mount on this flash is metal, and you can live with it.
  • Gluttonous when used intensively.


At the moment, it is very accessible on the secondary market, and at an attractive price there are copies that are little used. An excellent choice for beginners and pros. I hope this review of the Canon Speedlite 430ex II has helped you. Anything to add? Welcome to comments.

  1. Tell. When you turn on the indication on the screen blinks - is this how it should be? Since when the flash is switched to slave mode, it burns constantly without blinking.
