For those people not in the Canon universe, a properly exposed picture from a good camera will be at "0", meaning the camera picked the proper exposure. With your limited DR, ETTR is used to protect the shadows on Cameras from a number of years ago (and present Canon cameras). Of course settings can be changed in any camera, but the ability to push and pull in post allows a lot of freedom in exposure latitude. Cameras with evf also have an advantage because what you see in the viewfinder is what you are going to get in the picture, plus exposure aids such as zebras etc. allow proper exposure on the fly.
wow .. this is nearly as amusing as the one thread where you stated that Sony lenses are better than canon's..
you clearly lack some knowledge.
if your camera sensor has 14 stops DR (no brand here)
if you shoot a scene that has 14 stops of DR in the actual scene you wish to capture, to capture it effectively you have to adjust your exposure so that the DR of the scene fits into the DR of the sensor.
that's maximizing the capture of the scene's DR with the camera's DR.
with ETTR'ing - you are shifting the highlights to the point of clipping - which insures that you are using all available DR headroom and thus maximizing the fit of scenic DR against the sensor's DR.
seriously you should try this - even on your sony sensor, your imagery will improve.
