To me there's definitely something wrong with the test, the only reason I'm asking is to find out what it is exactly?
To me the problem seems to be that he's viewing all the other cams in their most flattest logs whereas the Red slate says only "RAW" and doesn't say which gamma space/log space it's being viewed in and the contrasty nature (dark blacks etc) of the footage seems that the Red is being viewed in Redgamma as opposed to redlogfilm which is presumably what it should be viewed at to match the other cameras. Can anyone confirm these suspicions with their better trained eyes? Seeing as how I'm not an expert at these things

+100 Alot of folks seem to be "in the know" but hiding this information from others leads to FUD, because many people have no idea how to use a RED. When i first got my scarlet i was called "an uneducated Amateur", for not knowing right off the bat how to process R3D's properly. The RED is completely different way of working and it takes time to get used to it. Yet there isnt really a starter point, on what that means, at least i havent seen one.
The best i can offer in getting the best out of it, is over expose by a half stop, and add more fill thank you think you need. keep the "black" above the noise floor, and remember that you can recover all the way from 100IRE and down. Rate the camera at 800, and let the image go a bit hot. In post drop it to 500 and you will be gold.
EDIT:
Awesome, great starting place!

By the way even the Zacuto test had the Red coming clearly on top of the f35 in dynamic range (and every other possible category)
As can be seen here:
So how is it possible in this guy's test the f35 obliterates the Red MX to such a degree?

Here's how to achieve proper Exposure:

Any camera can produce crap if you give it a lousy grade; I know, I've done it... hopefully I have a clue now!
And you can get lucky; I have stills shot on a ten year old pocket Leica digicam that look as good as anything I've shot in the last year, at least at low res.
What I want to know is, how exactly HAVE Arri managed to get more DR out of their sensor than RED? RED have plenty secret sauce - Raw, HDRx etc. and of course Dragon to come - all cool stuff. What have Arri done to get their measured DR on their existing sensor? Have they traded off something else? Why, technically, does it appear 'better' than RED on this measure?

5D MK II with 11.2 stops?
Please let me buy the 5D that made that test!
I'll buy

as I understand it dynamic range is all about photosite size. (well other things play a role but that's the most important) as the size of the photosites determines the light gathering capabilities and such. Red's Photosites are around 5 microns, Alexa is about 8 or more from what I remember.
The bigger your photosites are the less of them you can have obviously as the size of the sensor can only fit so much of them. So, since photosites comprise pixels, that means the bigger your photosites the less pixels you have and thus the less resolution. So in short, Arri sacrifices resolution for dynamic range. Red has super resolution and thus less dynamic range because its photosites are smaller.
