    True, but you'd have to ask the Norwegians about that, as they made that decision.

    Nice find Lars.
    Log profile is utterly irrelevant on this camera and it won't expand the dynamic range. You have the RAW output - you will never get better than that. This is the whole point of this camera...
    RAW via HDMI is a nice idea.

    I succumbed and bought one. 
    I will test more fully over the next week. Ergonomically from a stills view it's very much a urgh. No EVF makes life very difficult for me but i do have the VF on order so maybe that will change things.
    Cine mode. DNG. It's heaven. This is all you need from a camera. I've side by sided UHD 8bit onto SDXC vs A7sII UHD Slog2/Sgamut and there's no joke. It's almost comical. The low end and the highlights are literally playing in different ballparks. What crushes the A7sII footage is the compression. Simple as that. So that 8 bit UHD is remarkably good. I'm pushing and pulling it and comparing to the same thing shot  FHD in 12 bit and it's incredibly robust - so much more than it should be.
    Over the next week i'll push and pull properly. I got it as I needed a lightweight B cam to my Red for a shoot - so i need to intercut and i'll be finding it's comfort zones side by side with everything.
    So far the best resolve post in in ACES. My fear with going into any 709 space is that the camera native spectral response will be outside of 709. All Sony sensors push red way out and it's easy to see with bright red subjects. If you don't debayer into a larger colourspace then those reds get clipped or mushed into gamut. I don't know enough about DNG support in Resolve but visually into ACES appears much better. The only other valid option i think is Linear in, certainly none of the BMD Presets as they're for very different sensors.

    It was using just the LCD panel that I had for a Pi rather than the Pi itself.
    Like this one

     
    If you actually did want to incorporate a Pi into the equation though, you could use an HDMI to CSI-2 bridge such as this one to get the signal into it in combination with OpenCV to make a solution with monitoring functionality such as false colour, focus peaking etc.

    Ok here are two shots, both CINE mode, one uncropped, one APS-C cropped.

    OK, here you go, 8bit , 10bit, 12bit all from CINE mode and a 14bit still- sorry it wasn't on a tripod so the camera moved slightly

    We really need that firmware update for shooting to SSD- I exchanged my 500GB T5 for the 1GB version in hopes it might fix the issue, but no, a handful of CDNG clips are still coming in with frames misplaced in the sequence, and I don't have the patience anymore to go through them and try to correct the order.

    A firmware update is out that fixes the CinemaDNG problems:

    The linearisation table is used by the raw processing software to invert the non-linear pixel values back to linear space. This is why you can have any non-linear curve applied to the raw values (with the purpose of sticking higher dynamic range into limited coding space), and your raw processor still won't get confused and will show the image properly. The actual raw processing happens after this linearisation.

    I'm not sure how to test other than by doing this, but here are two DNG's,  the first is a frame from CINE mode, a 4K DNG sequence (A001_002_20191105_000001.DNG), the second was taken in STILLS mode as a single DNG (SDIM0188.DNG).
    Obviously the frame from STILLS mode is larger, but if you scale up the CDNG file, you'll see the framing matches, so no cropping (other than the vertical cropping to make it 16:9).

    Yeah, I totally could, it’s just that being able to ditch the SSD hanging off the side of the camera is the main pull for the 8-bit raw; if I have the SSD attached, I feel like I might as well go ahead and shoot 12-bit.

    This isn't going to sell the camera to anyone, but I will say, having completely written off the 8-bit raw before I even got the camera, I was intrigued by the article here to give it a go, and while you can't push the grade like you can with the 12-bit, having the benefit of being able to adjust the white balance after the fact is really great, and I'm totally sold on using the 8-bit. Just sucks that a fast UHS-II card with a fraction of the capacity is more expensive than a 500gb T5. (Or half-glass full, awesome that a T5 is cheaper than a fast UHS-II card with a fraction of the capacity!)
    Shot with the Sigma MC-21and the Canon thrifty fifty (which is a horrible combination btw, the slowest focusing I've ever seen, they're both going back). Works great in manual. Looking forward to some stabilized L-Mounts.
