Cactus X-TTL Cross-Brand TTL Firmware Upgrade for FUJIFILM Cameras Now Available

Share

Back on March 24, Cactus announced that they are working on a free firmware upgrade on the Cactus V6 IIs and Cactus V6 II transceivers to support cross-brand wireless TTL on Fujifilm cameras.

They also launched a dedicated website, and told us to stay tuned for updates, so I visited that special Cactus page a few times every day for almost 3 months now and finally something happened :)

Today, Cactus finally updated their X-TTL website. Here is what they say:

The X-TTL firmware 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.

The Firmware update to support Fujifilm cameras is available now, along with support for Sony and Sigma. More brands will follow.

The first wave of firmware releases will be for Fujifilm, Sony and Sigma. Other camera systems, i.e. Pentax, Canon, Nikon, Olympus and Panasonic, will follow one by one as we complete system integration on the V6 II.”

PRESS RELEASE

Available now! Download the FREE firmware upgrade on the V6 II and V6 IIs to have wireless cross-brand TTL on Fujifilm, Sigma and Sony cameras.

Hong Kong, June 16, 2017 – After much anticipation since our announcement less than three months ago, the X-TTL firmware for Fujifilm, Sigma and Sony that supports cross-brand wireless TTL is available NOW!

To get the free of charge X-TTL firmware, simply download the latest Cactus Firmware Updater and you will be able to choose from available camera systems. The X-TTL firmware, 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 time (1), now also supports automatic TTL exposure in the same cross-brand environment, both on-camera and off-camera. The table below shows detailed TTL compatibility among brands.

After this first wave of firmware releases, other camera systems, i.e. Canon, Nikon, Olympus, Panasonic and Pentax, will follow one by one as we complete system integration on the V6 II. 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 transceiver.

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.
