I have used my V860iiS and I've found my flash to misfire from time to time when it's on the hotshoe. This is the latest firmware on the flash and latest firmware on my A7iii.
Battery capacity is quite incredible. This cheap flash has no weather seal so this is not a good thing for Pro application in my opinion.....unless you live in the a rain free environment :P
If godox introduced weather sealing this would be a great improvement.
Also just remember the godox V860iiS does NOT emit any red focus beam either. Mirrorless cannot really use it anyways.
I'm finding a lot of folks on Fred Miranda shooting both mirror bodies (Canon/Nikon) and Sony mention how either A7iii and A7Riii struggles in low light auto focus. I sure wish the mirrorless would be identical in performance to mirrored bodies.
Even the Godox TT685F emits a red beam that appears to help my Fuji X-t2 a bit in low light. I know my sony version of V860iis flash does not help the camera at all.
Does it misfire a lot? I am migrating from Canon to Sony so I want to make sure I have competent run and gun lighting. I have been using the TT685S on my a6500 without any misfire issues and was pleasantly surprised to get the burst speed from it as well. I was hoping the V860iiS would be an upgrade in speed performance due to the Li-ion power.
I have not needed weather sealing thus far. Most of my events are indoors and weddings during fair California weather. Beach shoots are the only time I would need some king of sealing. I have added gaffer tape around the flash/trigger connection for a little added protection
I have yet to use my a7iii in a low light event/wedding. I am looking forward to seeing how it performs. I have a wedding in a couple of weeks so I will find out then. I am used to shooting with a Canon 6D and the a6500 and haven't had any issues with locking focus. Hoping the a7iii will be up to par with those at least
I turn off the focus assist beam on all my bodies, flashes and triggers. I don't want to be distracting and draw attention during ceremonies
