TTL without Boundaries! Cactus launches FREE firmware upgrades on the V6 II and V6 IIs to support wireless cross-brand TTL.
Hong Kong, March 24, 2017 – Just nine months since the release of the Cactus V6 II and Cactus V6 IIs, Cactus is now launching a series of brand-specific firmware upgrades to transform the cross-brand HSS flash triggers to one that also supports cross-brand wireless TTL.
The new X-TTL firmware versions, apart from supporting cross-brand high-speed sync (HSS/FP), remote power and zoom control of Canon, Fujifilm, Nikon, Olympus, Panasonic, Pentax and Sigma flashes all at the same time1, NOW support automatic TTL exposure in the same cross-brand environment, both on-camera and off-camera.2
The first wave of firmware releases will be for Sigma, Sony and Fujifilm. Other camera systems, Canon, Nikon, Olympus, Panasonic and Pentax, will follow one by one as we complete system integration on the V6 II. All these X-TTL firmware versions are free of charge for V6 II / V6 IIs users. The new firmware is system-specific so users simply choose the corresponding system when updating with the Cactus Firmware Updater. Once installed, the V6 II / V6 IIs is transformed into a cross-brand wireless TTL flash trigger.
This unique function gives photographers an unprecedented flexibility. The need for matching flashes with the same camera system for on and off-camera TTL flash photography is over – TTL without boundaries.
