Technical shooter

You seem to be having a discussion about dynamic range with someone who mis-understands it. The alexa has moved on as well and improved over the years. The 65 and the Amira are both different cameras delivering to different segments. For feature production the Alexa kits out better, for run and gun and small shoots the c300 is king. It is much more the sensor specs that get a camera to set. Workflow is the biggest c300m2 issue right now. If you don't record canon raw externally you don't get 15 stops. (though looking tests that show 12 stops look like they were done on broken cameras.)
