I picked up a couple of the V860XS dedicated hotshoe Flash for Sony this past weekend. It took me a little while to figure out the HSS on this flash. When you mount the flash onto the hotshoe of the Sony A6000, A7II or A7rII the flash will default to a shutter speed of 1/250 not matter if you are in manual, or shutter priority. I n aperture priority you are still limited to a max shutter speed of 1/250 or camera synch speed. The Secret, is that you will have to press the “synch” button on the flash to enable HSS with the V860 flash. This is totally different than the TT685 which with that flash, once you go past the camera synch speed the flash will automatically engage HSS and when you return to normal shooting the flash will shoot in the normal mode without the need to press any buttons.
The flash performs exactly as the TT685 in wireless mode allowing you to use the 860 in the hotshoe as an master to control another V860, 360II, and 600X. I have tested this and the flash perform as designed and the exposure is spot on!
Here is a little video that I made to illustrate the small inconvenience….
