Vangabriel, hi and don't fret about the meter. It is a selenium type meter and the black and white bars serve the same purpose as on any other selenium light meter, to compensate for the lack of linear response to varying light intensities. Ranchu has already given you all of the info that you need to figure it out. Just go someplace quiet with another light meter and start comparing the readings. I am positive that everything will become clear in a few minutes. 😉
I do not have a 7, but I understand that they are a very nice camera. My L1 is a gem and the 7 is an improved, upgraded version, actually the next series, I think?
