I'm currently shooting with a Nikon D70.

For flash I use a SB600.

I use the following lenses:

Nikon 60mm f2.8D Micro-Nikkor (macro 1:1) - currently my most used lens.

Nikon 18-70mm f3.5-4.5 AF-S ED - general use lens

Nikon 50mm f1.8D - great lens for low light, inexpensive.

Sigma 70-300 f4-5.6 - telephoto zoom with 1:2 macro capability. Used this for macro shots before I got the 60mm. Still useful when you have to stay far away from the subject ( working distance ~ 1m at 1:2). Unfortunatly, for general use you really need to stop it down to f8-f11 to get decent results.

A set of extension tubes which take the 60mm to 2.4:1 and the 70-300mm to about 1:1.2
