i have a project coming up where I can use my 5dm3 or a red one mx…(since I haven't shot on the red mx) which one do you think is better for a feature project??
Hate to say it (on an ML forum), but any time you have a chance to use a "pro" camera, use the pro camera. That's not to say that the RED One doesn't come with its own set of issues, but it's field proven over and over and it's a professional camera. ML is a hack, a damn good one at that, and one that I certainly like to use, but a hack nonetheless.
What you get with RED One is access to PL mount lenses, slow motion, no BS monitoring and playback, good audio inputs, and a raw format that technically doesn't require any transcoding of any sorts since most NLEs can deal with it natively. My main annoyance with the RED One is its proneness to crash or develop weird quirks that require restarts. Usually the rebooting process can suck up to 3 minutes which on a set can feel like forever. Plan accordingly.
