7D : metering problem

Hello,

I do observe following situation with 7D. Av, evaluative metering. For exemplification purpose, let us suppose a scene with rich contrast, say a medium/low toned subject, 10...15% of frame, on light background.

1. When shooting in One Shot camera sets a certain exposure. This exposure would be almost ok, I do observe camera is taking in account focus point and luminance of subject.

2. Same scene, this time in AI Servo AF , continous focus on subject, I get a different exposure, usually -1/3 ... -2/3 compared to situation at 1. But there is always some difference in exposure vs. situation 1. In my thinking this should not happen since the camera knows where the subject is and subject is continously focused.

Has anybody here observed this? Is this a bug?

Thanks for you contribution to finding out what happens.
