View Overview


Fire up to 15 compatible Speedlite flashguns over distances of up to 30m. The updated Canon Speedlite Transmitter ST-E3-RT(Ver.2)² enables all the wireless radio features of the Canon Speedlite EL-1, including wireless second curtain synchronisation, low power (1/8192) output and Flash Exposure (FE) memory. It also enables support for some of these additional capabilities with other compatible Speedlite models. The 2.4GHz radio frequency triggering operates reliably, even when shooting outdoors and around corners, meaning that having a direct line of sight is not required.

Up to 15 cameras can be triggered at once, for synchronised shooting.

How it works

  • 1

    Click Add to Basket

    Choose a product or create a basket of AED 500 or more

  • 2

    Select Pay in Installments

    Choose 'Pay In Installments' payment option at checkout, choose your bank and an EMI plan that works for you

  • 3

    Place Your Order

    Review your order, enter your card details and click 'Pay' to place your order

Representative Example:

  • If you have made a purchase of AED 2,500 & selected a 3 month payment plan and your credit limit is AED 6,000 then your bank will block your credit limit by AED 2,500 and thus your available credit limit after the purchase will only be AED 3,500. As and when you pay your installment every month, your credit limit will be released accordingly.
