Cactus Announces X-TTL For Nikon, Free Firmware Update

When Cactus first launched their X-TTL technology a while back they made the interesting decision to start it with support for Fujifilm, Sigma, and Sony; not the traditional powerhouse TTL technologies of Nikon and Canon. Well, they have since added Pentax and Panasonic/Olympus support, and that left only Canon and Nikon still unsupported by the technology; until today, with Cactus announcing the availability of X-TTL compatibility with Nikon.
