The tests were done in the same way that I have done tests in the past so as to facilitate comparisons.
The G&D charts, used this time instead od DSC as they're smaller and easier to travel with!
The charts are exposed for T2 at an EI of 400 and then the lens is stiopped down in half stop increments to T22
The chart is then exposed for T22 and the lens opened up at half stop increments to T2
The lens was an Ultra Prime 50mm and all lighting was daylight balance, a pair of 1.2Kw Arri Fresnel and a pair of 200W PAR's
The Alexa material was loaded into Iridas Framecycler and rendered out a single DPX frames and also to Rec709 using an Arri de-log file.
The RED material was loaded into Redcine-Xe and rendered out to REDFilmLog and REDGamma2 in each case using RedColor2.
The SI-2K material was rendered out in Iridas Framecycler using a standard SI 5600 look
The Canon 7D material was loaded as Quicktimes in to Iridas Framecycler and rendered as 10 bit DPX
The Panasonic material was converted using Panasonic P2 software by Camera Centre in Gothenburg, the software refused to run on either of my machines!
These were the settings reccomended by RED and ARRI.
I stopped rendering material from any camera when I couldn't see where the exposure indicator at the bottom was.
I don't doubt that better results can be had from these cameras with individual tweaking but I wanted totake a baseline approach.
The original R3D files can be got by right clicking on the links at the bottom of the page.
I'll also add Epic frames as well as Alexa RAW soon as I can.
As usual click on the thumbnail for a full res DPX file.
