When you change exposure control (Center weighted, spot) on the em-5 does it affect how the histogram or the highlight/shadow blinkies display? Also, when in the left dial video mode is the exposure control fixed in multi-zone metering mode? Thanks!
To your first question, yes. You are effectively using a different metering technique so the overall exposure will change. A spot meter reading off snow would give a very different exposure than a spot meter reading taking off a dark jacket of someone standing in snow. Don't know the answer to your second question.
