No HSS on the XPro2 ? I guess that means that the new Nissin firmware kills the HSS for the XT1 as well. Not good news for me. I think I need to wait until tomorrow for my X-T2 then start exploring ways round this. WANTED: Person with expertise in identifying flash protocols from data using an oscilliscope. Please contact me by PM. I would like to compare/contrast XT1 and X-T2 flash protocols for TTL and HSS.
