Does not come close to the original ....

Unfortunately Yongnuo are on its website at: "Third party replacement for original Konica Minolta FS-1100" and "Applicable Flash: Minolta 4000AF, 2800AF, 1800AF, 1200AF and wireless flash receiver".
Therefore me two of these adapters have been purchased in order in my strobist studio my Minolta 4000AF in conjunction with Phottix Strato igniting spark triggers. Basically, this YN-H3 also do this, but unfortunately they do not wake up function, ie: go the Minolta after 10 to 15 minutes in battery-saving mode, I can not wake up again with button pressed halfway :-( are quite different since the original Minolta FS-1100, of which I have also three. These bring the 4000AF with no problems from a deep sleep, whether mounted on the camera or on the radio triggers!
So if not his flashes off every fifteen minutes and will turn it back on, so that they ignite, you should rather pick up the original.
