Does the Cactus V6 work with my camera in TTL mode?
The V6 is a manual trigger, so there are no automatic readings / exposure settings sent wirelessly to the flash.
It is just an advanced manual trigger that allow users to remote power control your TTL flash that runs on Canon, Nikon and Pentax systems, even from your camera.
So you can imagine the V6 as any other manual trigger (such as the V5), but instead of you physically walking up to the your flash to adjust its' power, you can now do this wirelessly! Of course there is a list of many other advanced features that normal manual triggers do not have that makes the V6 special.
