The point you raised is that Canon have priced you out of making your project... Forcing you to either choose talent in front of the camera, or features in your camera.
I put forward the counter argument that Canon have already created a budget indie camera that shot Shane's film and made him a good income and received praise from critics and viewers alike. In fact, they added a better codec, better low light, less aliasing and moire in their 5DIII upgrade.
Face it, Canon have provided cameras that any indie film maker could shoot a watchable film on, if they have the script and talent.... prices from $500 to $30,000.
I'm sure we'd all prefer more features.. resolution, dr etc.. and we'd all prefer things to be cheaper.... But the art of making an indie project succeed is to find ways around such problems and use your talents and script to drag people into the art.
Anyone sat on a script thinking they need to wait to shoot it in 4K, or with 14 stops DR, or must have raw, or must have x lens are just wasting their own time.
If you have a good script, buy a D800, a 5DIII, a 6D, a GH3... hell, grab a 2nd hand GH2 or 5DII.... Learn to light your scene and get pristine audio... and go do
