2 serious bugs with 3D tracking and metering

1) If you use ASF-C with 3D tracking then the metering (spot/matrix) always supposes that the subject is in the middle of the frame instead of under the selected AF point.

2) As the AF point tracks across the screen, the metering does not follow the AF point

This is a serious error that could lead to badly exposed pictures when using 3D tracking.

the first problem is worse than the second one but both should be resolved. Knowning Nikon, I doubt that they will ever adress it.

As a workaround you can take the following measures
always use the center point as a starting point for 3D tracking and

always have cf-f1 on when using 3D tracking: this locks the exposure of your subject when you alf press the shutter

It does not solve the problem completely because when the lighting changes, your subject will be incorrectly exposed anyway.

Sorry guys, I really whish my first post since I recieved my D300 would have been more in the style of "Yeehaaaa" but helas
