    Interesting, but for me I care more about DR than global shutter. I hope it doesn’t impact DR at all

    Too bad it is monochrome...

    I'd love a real monochrome camera.

    ps : thinking about it, I can see myself having the future Panasonic FF camera and a mft monochrome as my 2nd camera during projects. Personally I always end up post processing around 20% of my pictures to black and white anyways. So might as well have the real thing.

    I think it's a bit interesting that the "APS-C" version is 4:3 ratio

    Wait, what? I thought M43 was dead again.

    No you are wrong.
    It was dead last week, this week it’s alive.
    But wait for next week.
    Dead. Totally dead.

    Global shutter. OK ,what is that supposed to mean?

    Like the CCDs of old... no rolling shutter. Essentially all pixels on the sensor are exposed simultaneously.

    It won't be monochrome.

    Just the same way that the IMX299CJK sensor in the GH5s is "based on" but is not exactly the same as IMX294CJK Starvis sensor that Sony offers on their website, it's quite obvious that if this sensor were to be used by Olympus it would be tweaked to their satisfaction.

    Changing from monochrome to RGB is a trivial matter of applying a different Colour Filter Array. This is how Fuji differentiates their cameras from Sony, despite using identical underlying sensors beneath the X-Trans CFA.

    The more problematic aspect is that Global Shutter cameras tend to have very low dynamic range. I'm not sure Sony has managed to do anything to solve this.

    Given the 43 fps frame-rate capabilities, its conceivable that Olympus might use smartphone-esque image processing to do in-camera RAW HDR, by processing and combining different exposures taken milliseconds apart, especially if it is free from rolling shutter artifacts. But that would be a big departure from anything they've ever done before. But not unprecedented - DxO does it with the "Super RAW" on their DxO ONE, released back in 2015.

    It has wrong size because of 1:1 aspect ratio so I doubt that we will see it in new OMD camera.
    But technology can be surely used for new OMD.

    I think that would be more correctly stated that all pixels are read simultaneously. With rolling shutter issues the sensor is exposed (all pixels exposed), but while reading one line of pixels at a time, as the subject moves lower pixels can change before the read happens on those lines. With a simultaneous read, you grab all the pixels at once, so no subject movement is recorded.

    Read, captured, recorded, exposed... whatever.

    When in the context of a shutter, I think exposure.

    How AF would work with global shutter?

    ScottinPollock Mu-43 Top Veteran

    I would "imagine" it'd be faster as the sensor readout is faster. But this assumes the processor is up to the task of keeping up.

    I don't see it being any different?

    Global shutter is just an electronic way to produce a result that is functionally similar to a mechanical shutter. The electronic rolling shutters that we use now tend to produce motion artifacts due to the limitation of their readout speed.

    But autofocus works the same way, regardless of whether you are using the mechanical shutter or the electronic shutter.

    For CDAF, probably faster or same at least, I agree. But my question was, are they making OSPDAF sensors with global shutter mechanism?
    Just curious, since this is probably first generation release and not much information is available (yet).

    ScottinPollock Mu-43 Top Veteran

    Yeah, because the sensor readout is the same with either.

    Now I don't know exactly how Panasonic does there CDAF, but since the EVF on the G9 is capable of 120FPS refresh, the much faster readout of the global sensor may indeed provide more time to the AF system.

    This of course assumes the camera can't adjust focus during the capture process. This seems a reasonable assumption given the G9 can't do C-AF faster than 20 FPS, which is the approximate readout time of the current sensor.

    But I'm just thinking out loud here.
