Disclaimer: the full specs aren’t out yet and nothing is officially announced New 1D X Mark II specs (via Canon Rumors) have just come out which reveal it to shoot DCI 4K in MJPEG format (4096 x 2610 and likely 8bit) just like the 1D C. However the maximum frame rate for 4K is now 60p! However at first glance there appears to be a glaring omission – that of Canon LOG.
