I bought a cheap -chinese-made- set of metallic extension tubes that I used with a Nikon D60 without having any issue. Today am trying to use them with a Nikon D7000 but for some reason whenever I use them -no matter which combination I choose-, there's always a light-spot dead-center on the photos, just like below:

Anyboody has any idea as to why is this happening?

This is particularly noticeable whenever I use my macro flash.

Thanks for looking!

Exactly the same problem. But it only happens with the Nikkor 50mm 1.8 for me. All other lenses work just fine. There is no spot at 1.8 for me though. But as soon as I increase the F number, the white spot starts taking up a significant are of the image.
