Since the display of Alpha 58 can no longer turn (my old Alpha 33 could this), a screen overlay is needed. You get a great selection and I chose luckily for this. The film is easily installed, you followed the instructions, is also no air bubble under the foil. 5 films and I still am going to probably have to buy 5nKameras because the attached sheet does not seem to depart again (unless I attribute this cause). The image is not tarnished, the film is crystal clear. Buy recommendation!
