Is the D7000 overexposure in bright light / probematic AF still an issue? -

Yes there was a huge AF problem, and also an over-exposure problem.

I tested 14 different cameras from the first batch, at a local store. The AF was garbage on ALL OF THEM. They also seemed to be an over-exposure problem in some situations, but only with some lenses, not all of them.

Now this year I tested a few D7000's again in the same store, and the difference was like night and day. They focus perfectly and the meter is one of the most precise I have ever seen. It's like a completely new camera.
