The films are ideally suited to the Sony Z1 Compact. All cut-outs are in the right place. Although the assembly is somewhat tricky as with all films and you should give it scrupulously careful that no speck of dust or Häärchen strayed between mobile and film ... but smaller air bubbles can be easily spread, for example. If the first attempt does not work, the film can be pulled off again and reapplied. Tip: Do not use a cloth but a paper towel (no toilet paper) with a glass of water for cleaning and drying. Cloth towels to lose tiny fibers, which then reflect in the film. New, unused microfibre cloths are also suitable.
