    Just in time for the olympics! Technologically, this has never been seen before - a full frame global shutter camera. For context, electronic image sensors typically having rolling readouts - one line of the sensor (which to some extent can represent one line of pixels in the final image) is read at a time. This limits the functional framerate, as without a mechanical shutter, you get rolling shutter.

    A global shutter means that all the photocells are read at the same time. Although they didn't mention, I find it likely this camera doesn't have a mechanical shutter at all. They did sacrifice some resolution (24 MP sensor), but that hasn't mattered in a while.

    The next question is whether or not the A1 successor will have a global shutter - and how much it'll cost to have a high MP global readout sensor. Given this cost $6k, I'd have to imagine the A2 with a global shutter would be $10k.


    edit:

    Another interesting tidpit is

    All three cameras will also add C2PA authentication metadata. C2PA is a combination of the efforts of the Content Authentication Initiative and the separate Project Origin initiative.

    There was a leica rangefinder that came out with this as well, but it seems like more mainstream cameras are getting it now (Although it's weird that the as7s3, a video camera, got it first? And not the a7rv or a7iv). It's something to "prove" that your photo was really shot by you in a world of ML generated content.

      Yeah i like my a7iv but not thrilled watching Nikon roll out massive feature rich updates, while the a7iv gets updates that cause issues with some cameras’ updating process. I won’t be in the market for a new mirrorless camera any time soon as I also shoot film but it’s going to take a lot to get me to buy Sony again.
