I've seen a lot of complaints about Canon making the sensor that automatically switches over to the EVF too sensitive. I completely agree. It annoyingly switches over to the EVF at times if anything gets near it. But I absolutely don't want Canon to change it.
If you notice, when you put your eye up to the EVF, there is very little lag in switching over to the EVF. As soon as your eye gets up to it, it's seemingly on. This is great. It reduces the chance of missing a shot waiting for the camera to switch over to the EVF.
Realize that dumbing down the sensitivity of the sensor would result in the camera not switching over to the EVF until your eye was that much closer to the EVF, thereby causing there to be a lag when switching over to the EVF. As annoying as the overly sensitive sensor is, I think it would be ten times more annoying to put the viewfinder up to your eye and have to stare at a black screen for a second while the camera switches over to the EVF. By making the sensor sense objects further away from the sensor, Canon has effectively given the camera a head start in switching over to the EVF, ensuring that by the time your eye is actually at the viewfinder ready to take a photo, the EVF is turned on.
