I'd file that video under Fiction along with quite a few others from Phase One.
Your pulling on a rope and I don't think you know what it's tied to.
I don't know you and your motives may be pure, might not, but I made mine very clear.
For the record, Phase and prior to that Leaf (when I had an Aptus) never asked, insinuated, implied, made mention of me saying anything false . . . ever.
In fact they we're very clear that what they wanted was the user experience and I think that's what I said then and now.
Once again, for the record the reason I didn't like Phase's video was I wanted a day for myself and our crew to rest and feel a little better as we came off of a lot of weeks of 18 hour days and I know I couldn't think straight, I doubt if anyone else could either. Everyone wants to make the best presentation in public.
Regardless no one asked me to use a Phase/Mamiya body and knew what camera bodies I used.
In regards to tethering c1 has been the gold standard for a long time. V3 was so solid that we could set it up, capturing to either two drives or a raid 5 and just leave it alone. Honestly, the only time we touched it was to change the naming.
V4 was new had some issues but were fixed, v5 bullet proof again.
I've found in our case if we want to tether without issue we use clean computers, clean drives and prepare the cameras accordingly with polishing the contacts, making sure all batteries are fresh and new, etc. etc.
People I know that routinely have issues with tethering of any brand usually have some other issues (see my sentence above) and/or don't really know the systems they use.
Actually, if you want to know anything about Mamiya, Phase or Leaf, just ask Yair. I've known him for 8 years, sometimes we've agreed, sometimes we've both strongly disagreed, but Yair is well respected in the industry on both sides of the Atlantic and will not tell you anything but the truth as he knows it and he knows a lot.
