Firmware Updates for Canon EOS C500 Mark II & C300 Mark III
Both cameras will now be compatible with Canon’s XC Protocol, which better enables them to be used in live productions and allows them to be controlled remotely via Canon’s RC-IP100 remote controller or via 3rd party controllers.
Both cameras can also now limit the 12G-SDI output to 2K/FHD when recording in resolutions at 4K and above. This allows compatibility from the SDI Out port with 3G-SDI devices.
We have also added the ability to use both the Monitor Out & HDMI output simultaneously. This brings the total number of monitor outputs to three, increasing flexibility in production.
