Not going to setup for preview of every shot. No real advantage to that one. Just as easy to hit the playback button as and when you feel the need. If your camera is set to lighting up the rear screen after every shot its going to have more negatives than positives. Slows things down, detracts from your subject, and that right moment. And you just know that right moments going to happen whilst your chimping. Not to mention that poor old battery taking a drain. Only an opinion granted, but in the days of 35mm !!!
