Good question

If you are using manual focus lenses, is the "focus point" (the center?) taken in to account when calculating the exposure in matrix metering or other modes?

Good question

I had no ideal so I picked up my camera to try and see. For a fact I can demonstrate AF point bias in matrix metering with a Nikon lens in AF but do not have a manual only lens. Took my 24-120mm and checked to make sure there was AF bias with lens set to AF. There was. Then I set the lens switch from M/A to M and the bias went away. Didn't matter where I put the body focus box...no exposure bias. So with that said, my thinking is that there is no focus point bias with a manual lens in matrix metering but you can still spot and center meter as normal. Really wish someone else would test to confirm.
