>>3807051>Does 5D have a real-time preview? Or do you need a mirrorless camera for that? My brother-in-law has a 400D and it only shows the pic for 1-4 seconds after you take the shot.No, you only need a camera with live view. 5D2 will do it.
400D doesn't have it because it's ancient. Generally speaking, if it films videos it also has live view. The opposite isn't always true, and some early cameras are able to provide live view but have no video recording.
