So as I was shooting my little twin cousins this weekend while they were collecting their Easter eggs, I was messing around with trying to use spot metering instead the typical evaluative metering. No matter what I did, my camera always spot metered the very middle of my composition. I was shooting wide open so I was using Spot AF and using my outermost focus points at times. I could easily be wrong, but I thought my 40D allowed me to spot meter wherever my focus point was, not only the center point. Is there a custom function I'm missing or something?
To confirm my speculations, I walked into the house and experimented with metering off open windows and the wall beside it. Yep, it was definitely ONLY reading the very center.
