I then bought a NEX 7 that have the same OLED viewfinder has as the nearly 300, - quite expensive single viewfinder for NEX 5N.
I have now almost 1000 photos with the NEX made 7 and can only say that the viewfinder is great. I have the display never actually used because the picture composition through the viewfinder is wesenlich pleasant. All information is as set in the menu, also shown. Changes will also be displayed in the viewfinder. This is with its 2 dials probably more important than the NEX 5 in the NEX 7.
Conclusion: If a NEX 5N has and a high-quality optical viewfinder would like, is here exactly correct.
One drawback is of course that the insertion contact the NEX 5N is blocked for other accessories such as microphone or flash. This should be kept in mind. Dehalb only 4 stars.
