exposes a FULL stop over in all Matrix metering...but is DEAD ON in spot or center exposures....what gives?

Any ideas....

Guy with a 100 macro had a similar overexposure issue with 2 samples, till he gave up on Tokina...

Hints...suggestions???

I didn't notice that with my copy, on a D200 and D300.

Did you check in an environment with even lighting? i.e., background is about same brightness as center?

I have been wondering that about *all* my lenses. But I think it's because I fiddled with something in camera and can't remember what, so I have weird exposure issues. Could that be it?

Does this happen if you point the camera at a grey card filling the frame?

My instinct is that exposures will be identical between spot,matrix and center in the above scenario.

Unless the lens has a mechanical defect (ie aperture blades not closing quickly enough, or mis-calibrated level) the lens doesn't have a whole lot to do with exposure.

This is on a D300. Confirmed against white and gray walls....I agree exposures should be identical but they are not. Lens is overexposing significantly in Matrix mode...any ideas other than back to Tokina?
