    I would expect the picture to look better at ISO 32,000. What were the other parameters? Did you use a very small spot to focus on the Abdomen? Is this a photograph of a B&W picture?

  • Vitaliy_KiselevVitaliy_Kiselev

    ISO 32000, but ISO is not all, as you need to know lighting used and other shot parameters :-)

  • RRRogerRRRoger

    Was this BW picture of the girl taken in poor/no light at ISO 409,000? I hate black and white anyway but this looks really bad to me.

    you have to change the HFR to 24p instead of 30. I think push left when it's on HFR in the menu

  • theconformisttheconformist

    Lost the manual already.. How do you record in HFR mode so that the resulting file is 5x slo mo (instead of doing it in post?)

    If the camera heats up because the battery heats up during charging, it may pay to get one of those micro electric fan (it is very quiet) and have a small breeze going. A tiny bit of wind will do wonder to convection cooling.

    Last two.

    @chauncy Could be, and the editor admits they didn't adjust beyond the LUT, but with the a7s any way (and maybe it's an Slog2 thing) I could never really get true blues, always that gray/blue as seen in the Slog3 footage. Here's hoping.

    Looking at the photo on the EOShd article it appears that the lens used is a Canon 85mm with a Metabones. If it is indeed that lens, or another Canon with image stabilization, and the lens stabilization is turned on, I'm not surprised at the jitters. Looks to me like the lens stabilization is fighting the in-camera stabilization. Solution- turn the lens stabilization off and let the camera do the work. It works brilliantly for me with Canon glass.

    "I was blown away by how much more color the FS7 could pull."

    FS7 was way better. But if you read the comments, they basically just applied the lut without any other adjustments. So the Fs7 was better. But I believe this just means the a7sii may need a little more work. I can tell right away the contrast and saturation need to be pulled up. Whether it can look as good as the fs7 with a few adjustments .. I can't be sure.

    @theconformist,

    I'm not too familiar with IBIS, does it have to be turned on or is it suppose to be always on automatically? Hopefully, in these example clips, it was not turned on.

  • theconformisttheconformist

    Slog3 seems to grade a lot nicer than Slog 2. However - watching the a7sII vs FS7 video, I was blown away by how much more color the FS7 could pull. Regarding Andrew Reid's clips - I hope this is not a testament to the IBIS!

    Here are some grades of some 4k Slog-3 footage from the Sony A7S II s that Andrew Reid made available for download here: https://vimeo.com/album/3613956

    The battery heats up when you charge it It also heats up when you discharge it. By putting a dummy battery in, that heat is avoided. I assume the dummy battery also aids in heat dissipation because I can run the camera over 3 hours continuously with an external battery and external recorder. Of course the processor does not work as hard when not recording internally.

  • theconformisttheconformist

    Regarding overheating, is this something that presents itself only with long UHD clips, or 1080 as well? Only when recording, or from simply being on? Is there risk of over heating from shooting short UHD clips but in a short period of time?

    It would nice if the USB port was Quickcharge 2.0 or 3.0 compatible; you'd probably be able to operate/record and recharge the battery.
