If you’re thinking about buying the Cactus V6ii for off camera high speed sync flash for your Fujifilm X-Pro 2 you might want to give this setup video a watch. The setup seems to pretty strait forward for a generic wireless transceiver, but Zed ProMedia can only get their combination to work up to 1/6400th of a second. They also bring up a good point that the new firmware 2.00 coming October 6th could break the Cactus V6ii HSS, but the update to fix it might include Fujifilm X-T2 support. Something to keep in mind.
