Canon Announces Macro Twin Lite MT-26EX-RT with Radio Transmission Support

On 29 August 2017, Canon announced its new external flash unit designed for close-up and macro photography—the Macro Twin Lite MT-26EX-RT. The new flash unit incorporates radio transmission capabilities as well as a lower minimum light emission, providing better control over light intensity even during multi-flash photography.
