If you're using it on the X-T3/X-H1, there's dedicated video AF-C setting with "sensitivity" (affects how much hunting) and "speed".

I'm already walking on razor's edge posting the sensor model number and datasheet. Certainly not gonna post pictures of the module inside the camera! If you look at the resolution and framerate combination, it matches perfectly with the spec. Sony Semicon is currently the only company that supplies consumer sensors in large quantity, and that's the only FF model available.

Yes there has been some 8K talk but the word is that A7SIII will remain a 4K camera, supersampled from 8K. There might not even be a continuation of the "R" line, "S" could be reinterpreted as "Superior"

New info from trusted source, good credibility but may be subject to change: The overheating is due to LSI and ISP being barely able to cope with over 1.5Gpps data from the sensor, which is likely the 60MP IMX551, same 3.76um pixel architecture as X-T3 IMX571 but equipped with 12-parallel ADC (higher number than A9). If that's the case, then the "S" in A7SIII is a drastic departure from the traditional concept that sensitivity requires low pixel count. Well, as A7III has demonstrated, it performs better in low light than A7SII, despite having twice the pixel count.

Mavo LF sensor datasheet, IMX410, shared by A7III:

On the regular 5in Video Assist, there's a "HDMI Range" setting that allows you to specify the range of input signal. It's very simple for Atomos to implement this, instead of treating all input signal as video range. ProRes can contain either full or video range data, it just need to be specified in the metadata header.

Totally expected this underwhelming result.

It's a known unresolved issue for many years, Atomos applies a forced data range to video range scale regardless of the actual range of the source, clipping highlights and crushing blacks, making the images look more contrasty. Fortunately the range can be mapped back in post, as demonstrated in previous posts.

True but it's not the one cure for all. Sensor readout speed has to be taken into account. Do you know the transit time of A7III's electronic shutter? Only 1/30s, note that this is independent from shutter speed, you can set shutter speed to 1/1000 and the sensor readout is still fixed at 1/30, resulting in rolling shutter when motion is present, or banding with artificial light. A9 on the other hand, has a lightning fast readout speed of 1/160s

If you watch the preview video from Newshooter, HLG has a minimum ISO of 1000. This is interesting because it seems like a "DR800" mode, exposing using ISO160 then a 3 stop push to ISO1280, then a digital pull to ISO1000. My hypothesis is that it may have slightly more highlight latitude at the expense of a bit more shadow noise.

Mavo LF shares the same sensor IMX410 as A7III, operating in 12bit ADC.

Nah, I have the datasheets, A9 sensor is fundamentally different from A7III. My point is, if Sony want to do it, it'll be a piece of cake for them. Do you know A7III sensor is actually capable of FF 4K 60P? And yet even the 4K 30P is cropped.

A9 has a completely different sensor with BSI and stacked DRAM. Readout modes, ADC, gain setting and colorimetry all require R&D work.

It's extremely unlikely there will be picture profile firmware update for A9, they can't justify the R&D cost for a video-centric feature. Most A9 users - sports photographers won't pay more for features they rarely use.

Yes A7III/A7R III have quite severe banding issue, simply because the sensor readout speed is too slow (rolling shutter). You'll notice banding on stills using E-shutter too. A9 has very minimal banding due to lightning fast sensor readout speed. GH5/5s are quite immune as well for the same reason.

The screen comes pre-calibrated with near perfect accuracy, recalibration is only needed after prolonged use and you notice a drift.

AF-S in reasonable light level yes, AF-C meh not really usable.

This one works with 4K 60P as well: https://www.lindy.ie/cables-adapters-c1/audio-video-c107/0-5m-cromo-slim-high-speed-hdmi-to-micro-hdmi-cable-with-ethernet-p7228 It's the only one with full metal connector casing.

HGST drives have the best reliability, especially the helium ones. I know HGST is now part of WD but it's quite different from WD.

This preview revealed some interesting details not announced by Fujifilm: HLG mode seems to have a minimum ISO of 1000, as indicated by the yellow text on screen. 4K 50/60P can now be recorded as in-camera conformed 25/30P, and it works with ALL-I compression. Crop factor 1.18x is now part of on-screen info display.

X-T3 V2.00 firmware preview:

The AF-S bug in video mode is there, someone did a video about it, start at 5:30

Oh that's peculiar, let's not spam this thread. Fuji's updated set of LUTs for XT2, XH1 and XT3: http://www.fujifilm.com/support/digital_cameras/software/lut/zip/F-Log_LUT_E_Ver.1.11.zip

Cool. Nope who's that

X-T3's F-log introduced some small but obvious changes in its colorimetry. X-T2's LUTs aren't fully compatible.
