Jon is correct, Zebra can be ON while shooting without being so distracting as FC and on some cameras you can specify a range (like 35-40%) and even have two different zebras and the best thing is that they aren't nearly as distracting to shoot with and have ON while you're shooting.
Two Zebras that are user selectable in a range from 0-100.
I'd love this kind of feature and used to ask for it all the time
