    Most BMD cameras boot up in seconds. Like 3 or 4 seconds. The G2 is the same.

    I’m sure they’ve sold many thousands of 6K cameras happily with their poor choice of EF mount.

    That's true of any sensor. The larger the sensor, the more likely it is to have faults. The rejection rate can be astronomically high.

    That’s a recent quote from Dave Newman. If you make a camera that uses cineform encoding in hardware and sell them to other people it’s not free.
