RED Ranger 8K S35 Bench: 16-17 stops Dynamic range overall. 15 Stops usable (over noise)

Let me start by saying that I sent a PM to admin of dvxuser, asking permission to post this thread, first I suggested in Nikon forum. I did a few minutes ago, so if this thread is not welcome, you can (admins) delete, but please .. read, I think it is best to publish here, as it is a mix of history and real bench.

I don't know the real history with RED, probably your forum was not ok with them, as the only forums about, in your web, are labeled as archived (an I don't have permissions to post).

As you may know, RED is now owned by other mid-major-brand (Im saying medium, cause to me its not a major)
Jarred Land, who sometimes I write to him and he respond to me via facebook, recently said me that he , and his friend Jim Jannard, are going to retire.

My history con cinema started as child, born in the late 70's, with passion, as probably many of you, as child, with the Spiven, Lucas and Coppola films. I love and hope for me one day ni short future to be able to purchase the 535B or the mk I.

Then when I started Cinemartin (2010-2019) on the early years, the F65 was the one I loved, the RED 4K120P was my second mid time cinemartin (before Fran8k that was inspired taking F65 in mind, global shutter, but in VV. Unfortunately while Phil Rhodes did a good job article, saying the true, the other one, Phillip Bloom wasn't able to properly start the prototype, which lead to my company dissapear, but that's another history).

2 Days go, on June 30th , I was able to purchase, to me, after the F65, the better 8K camera.Not only by the few units produced (500 aprox in total, but less than 100 for the s35mm)

I need to note, that, to me, and many others,

A) as less size the sensor is, better dynamic range. As opposed to current FFrame sensors, VV etc.

B) The DMSC2 Helium is better in recording than DSMC3. DSMC 3 has HQ, .. and LQ so only 3 compression modes, while DSMC2 's are user selectable up to 2:1 (or 1:2) on RAW ratio compresion, which is best than current DSMC3. DSMC2 tops at about 525MBps (just the same as Cinealta F65) with SSD SATA indide, which is , far superior than moders SSD drives, as modern SSD drives are TLC, and Sony, as well as RED, used SLC (thats why the media were so expensive).

On todays days all people say, ouuuaaa my SSD TLC is , e.g say 15 GBps but hey the y count on infintite threads que queue depth. I know cause I had the first Intel g80,g160 SLLC drives, and I also have someoptaner (another superior league), BUT THE TRUTH is that you need to measure Q1T1, that means pure sequential, true intraframe, I meant, frame by frame encoding.

Being said that, now I paste a video of my recent purchase (filmed with F65 & Master prime), spotting me and the RED Ranger.

I plan to do a Benchmarkt, probably tonight, sharing results probably tomorrow


Note , to see the above video at the master original H265 main 10, Hight profile at 8K50P fro the Sony Cinealta F65 use this link (is about 10 GB for a 4 min long)



Thanks Jarred Land ( https://www.dvxuser.com/members/jarred-land.2/ )
 
Hi me tests conclusions are,
16-17 Stops of Dynamic range, very similar to the F65.

Note the compression ratio 2:1 , better than DSMC 3.

I still prefer the F65, cause at same resolution, has same D Range buts is Global shutter, and with Rotary ND filters, as oppposed as a the (good idea altought) interchangeable ND filters on RED. F65, abeilt at a lower DR, like the Alexa 35 Xtreme, the Cinealta has the option of 120P in 8K, something that even not the Alexa 35 has.

F65 is the Saint Grial of Digital cameras, and the second close to, is that Ranger, probably they made about 33-99 units, consiudering the shre of the aluminum body (who's serial is equal to all, indiferent of the sensor size).

Live recording (setup, etc.)

Note: I recorded at many Aperture from T22 till T1.3

A discover that when really shines is at low light, while the highlight are not bad at all, for the highlights (the opposite of dark scenes) the better is the Cinelta F65.

Basically F65 ads a bit of grain, but its very similar to the grain found in the film (analogue) cameras like the ARRI 535 (which I hope to be able to buy as my top)

Close to, but not T1.3

while close to, very close to T22, below

So, as you can see (and please rememeber that I am for this pics, using capture screen app integrated on win10, so not 444, neither probably 422 or 422 8 bit);
That camera goes so well on dark scenes, I mean if you cannot afford a higher aperture (say T1.3-T2.0) or , better, if you prefer to use as less light as possible in any scene.

THATS GORGEUS, better or close and better than Sony A7S mk's series













Notes: The reader RED MINI MAG, is slower than the Sony SR-01, both over USB 3.0

Shared material, the RAW RED files are conatined in a .7Z file (no .zip, need the 7z free utility) at :



Considerting the SNR 1 and SNR2, if we go to find the USABLE pure Dynamic range then this camera has 15 stops of pure usable (over SNR 1 & 2) dynamic range

Look at the 1stop is over (one pure step over base noise line) , BUT
iF YOU SEE THE PEAK AT THE BOTTOM LEFT OF STEPO MAKED AS #1, then mmeans that this stop is in SNR , so

The really usable Stops of Red Range Helium, at best compression ratio, at 8K 23.98P (note that RED does not allow 23.976 as opposed to F65, as red round to 2 decimal)m ARE 15 Stops, similr to the 14.x number found on passmark, so that probe tht my test and setup is OK

The first clip I shoot in the first message of this thread was recorded on Sony F65, now I will made a short clip using the RED Ranger
