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

I have two D7000 bodies (as well as two D90's) and never had any exposure issues with the D7000's. Out of 26 AF Nikkor lenses, I've only had a back focus problem with one of the D7000's when using a 20mm/f2.8D lens. This was able to be adjusted (by me) and it works fine now. The same lens worked fine with the other body.

I have recently experienced oil spots with the first D7000 , now nearly two years old - heavens knows why it should start happening after all this time. I've just accepted that 'wet-cleaning' sensors is a part of life with digital cameras.
