    Hope you don't mind me asking but how do you know this? Are the specs for the sensor they're using online?

    Is this your observation or a stated fact?

    A combination of observations and insider info.

    Are there any benefits to having the "fake" information derived from the original readout? Or is this simply a useful marketing tool for Sony?

    Mostly a marketing tool so people perceive it as on par with those CineAlta cameras.

    With Slog3 on the a7siii (iso 640), does one have to still over expose by 2 stops? 

    You can download a sample, shot at 0EV and see for yourself.

    On the comments he says that was 4k 30 on both but he does not recall if HQ or not....

    It was shot in 4K normal.

    R5 8K/4K HQ: 21ms

    R5 4K normal 24P to 120P: 8ms

    A7S III 4K 24P to 60P: 15ms

    A7S III 4K 120P: 8ms

    Hmm.. so now he's actually advising people to ignore the overheating tests. The plot thickens..



    This was tested in Florida under direct outdoor sunlight with ambient temperature of over 38C.

    A7S III lasted 23min shooting 4K60

    R5 lasted 34min shooting 4K30 HQ.

  6. None of the 1080p modes on A7S III are supersampled from full sensor readout, 24p to 60p are pixel binned, 120p is pixel binned and lineskipped, 240p is futher pixel binned lineskipped (to 1420 x 804)

    Then would you agree that in general a 12MP camera (with more moire/aliasing) usually results in a softer image than the

    26MP 6K oversampling cameras for 4K video, DR being equal?

    Yes, with Bayer sensors, 1:1 readout is always softer than oversampled readout. Strong OLPF that combats moire can make it even softer.

    So there is no oversampling for 4K. How could this match the IQ of the X-T3/4 and all the other 24-26 megapixel cameras for 4K video?

    My X-T3 is oversampling from 6K to 4K.  Seems to me the 422 or 16 bit raw wouldn't matter much if the lack of oversampling results in a softer

    image.  Or is this new 12 megapixel sensor a major new technology?

    Oversampling minimises moire/aliasing, it does not directly correlate to better DR.

    BS maybe.

    "In-sensor scaling" = pixel binning or oversampling...That is the question. Because binning, skipping, implies you are not sampling all the data, but with averaging and combining data from all photosites, the story is very different.

    I am curious how the 12K RAW stuff does not infringe on RED's patents BTW.

    Changing the CFA is enough?

    I doubt that.

    Well put.
