Ok, I have the GX7 and GH3. I assumed based on comments from the online community that they were not capable of HSS. However, I recently came across some other posters saying that the GX7 (and implication GH3) do have this capability. Could someone please clarify? Sorry if this is already covered, but I did a search and came up with conflicting comments. If it is possible, what equipment and set up do you need. Ideal would be a multi-point speedlite setup on a wireless trigger. BTW, I tested the Yongnuo 560 II (which has the wireless trigger built in) and was able to push SS on the GX7 up to 400 with just a bit of banding on the top.
