I have an AF-S Nikkor 18-135 mm lens. While I initially suspected an issue with the camera, I found that my two Nikon camera bodies work perfectly well with other lens, and this lens works with no other Nikon body. When I say "work", I mean that the pictures I take are all over-exposed when on automatic. In normal light, the flash always pops up, and when I take a normal picture in normal daylight, the pictures are all washed out through over-exposure. I took one camera body (a D80) into a repair facility and they said that all the sensors, etc. were perfectly fine.
So I am wondering if this could be a lens problem, which it seems to be, and what is going wrong and whether it is fixable. Has anyone encountered this problem, or have thoughts on the likely causes of the problem?
