F35/F65 Sony CineAlta F65 Dynamic Range bench

[AlejandroMartin]

Hi, using my own setup, I got some nice material.

Date of recording: 15 June 2026, 22:00 hr (10 p.p Spnish Time)
Location: Lloret de Mar
Camera: Sony CineAlta F65 R (Global Rotary Shutter)
Lense: Arri Master Prime 50 mm
Display to Charts: Samsung QN700C at 4K (same res as RAW from F65), as TV supports 8K, but was at 4K
Monitor Brightness: 1400 NITS
Lights on recording:; none


I use this kind of setup, see bloew pics, but by the night, at about 10 p.m, so with no sun



this on field pics are using cheap mobile



all scenes recorded with no light, only the light from the Samsung monitor (at max 1400 NITS brightness)



I used as well following charts on the TV, so total


























I uploaded and share a folder in mega dot nz to share , but importatn images results on next

Distance from Sensor to TV about 3 to 3.33 meters, in front, as horizontal and perperdiculare better aligned as posible.

I see, correct me if I am wrong, 16 stops over the noise floor.

I Did many test, to this chart, 25 shots, from T22 up to T1.3, any step was a line (small or big) on the Arri Master prime


To me, on below grab, I see 16 STOPS over noise floor, 17 stops counting the just within noise floor, and 18 stops, but hey be aware that Im not sure at all as the chart was not coloured, just black to white. Fotget the "AFter" tag, its just same as "Before".

But what I know is that the colours aro so goos, se more below





This to me, bewlo, is about 15 Stops




Below at T9 as T22 and T1.3 were not good (remember filmed on night with no more ligth that the TV in front of sensor)

Green channel at T9
16 stops over noise




Green at T.9: down to visible 14-15 stops, this TV altougtjh supports 444, with the NVIDIA Quadro RTX 6000 I was using a display link (usb C to HDMI) so not sure if the picture shown was 422 (as I suspect as camera records in 444, so red green and blue should be equal)




Check the blue



Whats your opinion ?

For those who want to look at the RAW files, or a selection I shared all the footage and in scene videos here

Also I made a post in compuwood website, high classic tech section

Sony CineAlta F65 Dynamic Range Bench

Hi, as I posted recently (yesterday) on DVXUser.com, the F65 from Sony has a Dynamic Range of between 15 and 16 stops generally, above noise. Thats superior from the claimed 14 stops usually its…

And finally a clip, showing myself with a lover in a PEPSI spot (PEPOUI), REC 2020 PQ
Using Arri hardmatte 50mm to apply for a 4:3 aspect ratio, like the original cine was. I even think in film in 1.19:1 like Alfred Hitchcock and some Sherlock Holmes shorts / movies, instead of the 4:3 (1.33:1)

Very interesting approach!

I'm curious, how does shooting charts on the tv compare to something like using the Xyla 21? Wouldn't you run into issues with isolating the patches or interference from the brighter stops when shown on a TV like that?

I may have to give some of the test footage a look, I've never seen RAW files from the F65. Thanks for sharing!

My resources doe not allow me to purchase Xyla's, and or use IMATEST, which are also a bit complicated. The easyiest way, give ever, a better result.
As if you use complex system , the results may get many escenartios, so more comples¡xity.

I did as more natural and pure, as I was able.

If you see the videos on the folder /Phone (TEL) from the shared mega . nz url link, you'll see that I was using only the light coming from the TV, so exactly what a pro will do using the X's 21 Chart

I've considered to use a Matter box (Arri MB-20 who can be seen on a clip on the phone folder) to get out other light, but on the end, as no light (no Sun) were there and no artificial light was ON) then no issues on interference. The AMOLED Samsung does not emit interferences (It0s not an old school CRT) and even if did/do, at the safety ued distance of 3 or 3.3 meters, ideal for the best suited lense, a 50mm (what you SE is what you GET) I think, that I did a one good aproarch.

A few minutes ago, I got an email from Sony EU, they agree with me on the 17 stops, but they are saying something .. that I prefer to not disclosure, they're so good.

I shown also Green charts, it 16.1 stops
