you guys should talk to me about these extra bits; alpa prices are a joke.
after Graham's post about the PIA for connecting the viewfinder (two knurled screws) it is making me re-think the solution I have going for mounting my i-phone adapter, to the Alpa.
my adapter has a hot-shoe foot, since it was designed for the Cambo which has a hot shoe. For the Arca, i am making an alternate base that fits the Arca clamp; for the Alpa, the options seem to be:
1. buy the alpa hot shoe adapter ($280!!)
2. I can offer an alternate base for my I-phone holder that screws onto the body just like the viewfinder or the Alpa HS adapter
3. I offer a custom hot-shoe adapter that fits the alpa and my I-phone holder that you leave on the camera for about $75
by the way, I expect to have the first production run of i-phone holders ready next week
