For a troller he's pretty responsive, isn't he? I want to give him the benefit of the doubt. Who said he needs to be a professional photographer? Such a camera needs to be tested by amateurs too, because it will be bought by amateurs rather than professionals.
I've asked him about the viewfinder, the most important part I'm interested in (the sensor is secondary to me):
"My plan is to give out all the bits and pieces I can
The viewfinder is BIG... not like the MX, but much larger than today's DSLRs... New viewfinder is pretty darn good. Big and bight, full information overlays, and the AF point lights are two-part: one for activated and the second for when you hit lock (second one works in theory, but I found it distracting so turned it off 99% of the time).
... No diaphragm coupled
... I wish.
However: The mount on a different version DOES have this coupler... I didn't get that one, but at the meeting I heard it was around."
