I just found out that exposure measurement does not tie to the focal point. In the same scenery, I can set the focal point to bright, or dark area, the exposure still come up the same. The dark is still dark , the bright is still bright, under both cases. That is true for P, Tv and Av. Is there a set up problem? The meter is set to "Evaluation mode". If I remember it right, The M and M2 have the exposure meter tied to the focal point. Any input will be appreciated.
