I dont see good results with the 5D3 and Hypersynch. What i saw on the pocket wizard site was what i got with my 5D3 testing. Line was at the bottom of the pic at 1/320,,,,,very dissappointed becuase my MKIV allowed me to got to 1/2000 w/o a line at all.
So what I do is use ND filters, fast glass, and shoot for shallow DOF for outdoor use. I much prefer the ability to use Hypersynch like I had with the MKIV but the 5D3 wont go there.
Im all ears because i use strobes outside. Hoping someone got it to work with an einstein,, that would give me an excuse to buy one if it will let you shoot with faster shutter speeds.
Im not a big fan of HSS and speed lights. I like that you can kill the ambient, but it has that look to it that i dont like. You can tell its been killed with HSS. You need to mess with ISO and too much in post to make it look presentable to me.....I would rather use NDs'
