Well, that was quite clear - thanks again!
I s'pose I just can buy some extension tubes, they may be quite useful with many lenses.
As I have no experience whatsoever with these - which tubes would I need? Should I stick to Nikon, or Kenko set is good enough quality (mechanical - as there are no optics)?

Kenko set (12, 20 and 36mm) does support the screw drive, so it should be fine with 80-200mm. With 36mm tube you would get 0.62x magnification at 80mm and 0.35x at 200mm (the longer the focal length, the less effect of the extension tube). Technically a full set (68mm) would give you a true 1:1 magnification at 80mm, but from my own experience it's a bad idea - 80-200 is just too heavy and 3 Kenko rings joined together will struggle to support it. They bend and lose the contact witch each other <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/sad.gif' class='bbc_emoticon' alt='' />
