this has been discussed...if you are in a museum and want to take a picture of a painting behnd a glass, the red light reflection will surelly ruin your pic...same for video, even if you press H you have to do it after the recording as began..and if you need to refocus during recording...u have to open keyboard and press h again..and again..and again..this way in kp50...its great...its just gone..no more red light reflections, no more opening and closing keyboard, wonderfull job of the development team and a good descision to implement this i think.
