One of my night school students asked about macro lenses for his D-80 Nikon,
Well! I love my Nikon 105mm f/2.8 vibration reduced $800 macro lens. It’s fabulous. It’s also expensive and really, really heavy. However, the images are superb and it makes for a great portrait lens (but you might need to soften the ultra sharp image in software).
Nikon also has a new 60mm f2.8 macro lens at roughly half the price. It’s smaller but not as good as a portrait lens.
Macro photography is great fun. You can do it anywhere just about anytime. And the images are terrific.
One tip: Buy a decent tripod as you’ll want to use long exposures to allow for sufficient depth of field.
