    I shot plenty on the HMC back in the day but you couldn't pay me to shoot on one now... Can't think of any reason to bring back that ancient camera that wasn't great to begin with. So many better options now.

    Yes, notably sharper.

    Not sure I grasp the reason.
    It's because the dual codec recording is made from a direct resize of the UHD frame. Generally in 1080p mode, the camera scans the chip differently, using pixel mixing which lets it get a wider field of view and faster scan rates, at the expense of some picture softening and some aliasing; other bonuses include the ability to use i.Zoom and the hybrid optical image stabilizer. When using UHD in dual codec, the field of view is slightly narrower and the frame rate is limited to 29.97 maximum and the hybrid image stabilizer and i.Zoom are not available.

    So there are reasons to use the native 1080p mode, but the bonuses it gives are offset by the fact that it's not quite as sharp and has some more aliasing. On the other hand, if you don't need 59.94p or 50p frame rates, and you're not going to use Hybrid OIS or the iZoom, then you can use the dual codec recording and the FHD that's recorded is pristine footage made from a scaled-down UHD sample off the sensor.

    That makes sense. Wow, some days my head gets overwhelmed. Good info. Thank you!
