The link to the 5DR vs Phase One test proves nothing.
They have no depth to the scene they're shooting. It's just some girl sat in front of a wall
If you want to see a proper test watch Kubrick's scene from 2001.
I am amazed at the willingness of people to learn such important stuff from non-entities on YouTube.
The guy spends 90% of it comparing resolution and is then surprised to find out two 50MP cameras resolve similar detail!!!!
This is a typical full frame shot and shows nothing. The background is completely creamed out. The subject is punched in, with nothing around it but thin air. You can't show the full way in which a lens and sensor combination renders a scene from such a dull shot.

If no one is willing to do some work and actually do a test comparing MF to FF in the real world with equivalent settings, then what's the point of debating without any comparative evidence? I'm a cognitive scientist, open-minded and willing to learn new things. That said, a valid scientific test, which is easy to do is all that's needed to make a useful point regarding MF vs. FF.
If the only difference is MF lens design, that's cool, however this debate was MF vs. FF cameras (and again, Caldwell says no advantage for MF lenses anymore; no point in a MF => FF SpeedBooster).
If an MF camera system (body + lens) is truly better than FF, I'd invest in MF. So far there's no comparative evidence showing this to be true (the only scientifically valid way to determine if there's a difference).

As soon as the 1DC drops below $3K I'm in. Looking for a small hybrid B cam to the UM46k. The GH4 is a great camera on it's own but it's very hard to match up with Ursa footage.
 

it comes close in terms of speed and accuracy but very far away in terms of usability. At least for video.

Thanks for posting that Cinema5d review. It's really informative.
With Technicolor Cinestyle installed on the 1DX II, he achieves the exact same DR as the 1DC with C-Log (those final stops look much darker but they are there indeed: note that the 1DC is shooting at f5.6 while the 1DX II is at f11):

Of course, I'd love to see footage that demonstrates this in a side-by-side (like the one on the other thread). Honestly, I would not have believed it based on most of the 1DX II footage I have seen, but this is concrete proof.
Is no one else shooting with Technicolor Cinestyle installed on the 1DX II?
Moreover, the rolling shutter on the 1DX II has been reduced to 14ms, which is incredible! That's better than the FS7 and Ursa Mini 4.6k.

Only A6300 comes close in terms of autofocus
