Paperweight
Nikkor 50mm/1.8 at f/16, cheap-ass extension tubes, Velbon tripod. I notice this has been hit a couple of times by people searching for Nikkor and extension tubes, so: I bought the tubes off Ebay dirt cheap, gave them a good dusting before using them, focus manually and use trial and error for exposure - which is just fine for macro. They are the most fun per pound I've had with photographic equipment since I spent twenty quid on a Zenit SLR in 1980 (and index-linked they win hands down).
