A refined, lightweight flashgun with power and capabilities that belie its compact frame, Canon's Speedlite 430EX III-RT improves on prior models with an enlarged display screen, simplified controls and the introduction of radio-based wireless TTL - previously the remit of the much higher priced 600EX-RT. The 430EX III-RT also boasts optical triggering, a guide number of 43 with 24-105mm coverage, movable head with integral reflecting panel and a 3.2s cycle time. All in all, on or off camera the 430EX III-RT is a wonderfully capable tool: Brilliant for portraiture, enormously cost-effective and packed full of photo-making possibilities.

A portable, powerful Speedlite flash that’s easy to use – on and off the camera
Take a new approach to lighting with a Speedlite flash that’s powerful, versatile and portable. Radio-frequency triggering makes off-camera flash easy to do, and opens up new ways to get creative with your photography.

  • Powerful, yet compact enough to take anywhere
  • Simple controls and an intuitive interface
  • Use remote flash to create the look you want
  • Shoot flattering portraits using bounced light
  • Integrates with other Speedlites as part of the EOS Family

The power of light in the palm of your hand
The new Speedlite 430EX III-RT is Canon’s most capable mid-range Speedlite flash to date. A maximum Guide Number of 43 at ISO 100 provides enough power to light subjects in a wide range of conditions, with the flexibility to work alongside additional flashes using the radio or optical remote control system. Plus, with a lens coverage range of 24mm to 105mm, or to 14mm via the built-in adapter, the Speedlite 430EX III-RT offers a wide or narrow spread of light which is controllable by the user.

Powerful, yet compact enough to take anywhere
A guide number of 43 (m, ISO100) means there’s enough power for most occasions.
The Speedlite 430EX III-RT weights just 295g and is only 113.8mm long, so there’ll always be room for it in your bag.
Powered by readily-available AA batteries, the flash recycles following a full-power flash in just 3.2s.

Simple controls and an intuitive interface
The controls on the Speedlite 430EX III-RT echo those of many EOS cameras. Shortcut controls give access to key features, and a control wheel allows quick adjustments to be made. A lock switch prevents settings from being changed accidentally. An LCD screen shows settings and shooting information at a glance, and is illuminated for low-light conditions.

Use remote flash to create the look you want
Speedlite 430EX III-RT flashes can also be placed away from the camera, to simulate light coming from different directions.
Using Radio frequency triggering, Speedlite 430EX III-RT units can be controlled from up to 30m away, and do not require direct line of sight with the camera. This means they can be situated in more places, letting you create even more moods and effects.
The Speedlite 430EX III-RT can also be remotely controlled with optical triggering, so it will fit in immediately with your existing flash set up. It can be fired from 10m away using the optional Speedlite Transmitter ST-E2 or the Integrated Speedlite Transmitter built in the some EOS cameras.
Use multiple flashes together in groups, controlling the power of each group separately. Up to five groups can be created, with a maximum of 15 flashes in each group.

Shoot flattering portraits using bounced light
A movable flash head allows light to be bounced from large surfaces, like walls or ceilings, creating soft, shadow-free lighting that’s perfect for portraiture.
A built-in reflector panel can be deployed to create sparkling ‘catch lights’ in a subject’s eyes, bringing their expression to life.
Fit the included Bounce Adapter to soften the light even more. A coloured filter is also supplied, which aims warm up the colour temperature of the flash’s output so that it more closely matches the colour of indoor ambient lighting.
The Speedlite 430EX III-RT can zoom its flash output to match the angle of view of the lens being used.

Integrates with other Speedlites as part of the EOS Family
Use the Speedlite 430EX III-RT with other flashes, such as the Speedlite 600EX-RT, as part of a multiple flash setup.
Control the Speedlite 430EX III-RT off-camera with a flash trigger, such as the ST-E3-RT, or with an EOS camera’s built-in Integrated Speedlite Transmitter.

Dual wireless flash triggering
The Speedlite 430EX III-RT can be fired while off-camera using radio-frequency or optical triggering, giving photographers huge versatility. When using radio-frequency triggering, flashes can be placed up to 30m away from the camera and do not have to be within direct line of site. This means they can be placed in many more locations, such as outside a room firing in through a window.
Optical triggering allows EOS cameras featuring a built-in Integrated Speedlite Transmitter (e.g. EOS 760D, EOS 70D and EOS 7D Mark II) to fire the Speedlite 430EX III-RT from up to 10m away, without the need for extra equipment.

    Are you eligible for finance?

    Applicants must be:

    • Aged 18 years or older from the application date
    • In permanent UK residence for a minimum of three years
    • Fulfil at least one of the following employment criteria:
      • In regular, permanent employment.
      • Retired from regular employment - With a minimum age of 50.
      • Not working through disability.
      • Self-employed.

    Note: All applicants will be subject to a credit reference check by the lender.

    Credit is subject to application and status. Warehouse Express Ltd trading as Wex Photo Video act as credit broker and not the lender. Barclays Partner Finance act as the lender.

    Can I repay early? If so how?

    No repayments are scheduled in the initial six-month deferral period. However, it is possible to pay off the loan, either by way of a lump sum or in smaller amounts. If the loan is fully repaid within the six-month deferral period, then no interest is payable, but a £29.00 early-settlement will be incurred. Such repayments may be made to Barclays Partner Finance by cheque, debit card or standing order. Unfortunately it is not possible to set up a direct debit within the deferral period. Further information on how to make such repayments will be set out in the loan agreement pack provided by Barclays Partner Finance.

    What happens if I don't repay within the first six months (deferral period)?

    Following the six month deferral period, Barclays Partner Finance will initiate a monthly direct debit payment for the remaining duration of the loan. Interest will be charged at a rate of 19.9% APR on outstanding balances (backdated to the first date of the loan). Late payment penalties and early repayment charges will apply from this point. Barclays Partner Finance will send a reminder letter approximately one month before the six month deferral period is due to elapse. Note: If you chose to spread the cost and pay monthly, interest is charged from the start of the loan, not from the start of the repayment period.

    What will I receive from the finance provider (lender)?

    Barclays Partner Finance will send a loan agreement pack approximately four weeks after delivery of the goods, confirming that the account has been activated and, from this point, it is possible to make repayments against the loan.
