I've had it since 2001. It's sharp and contrasty, with very low distortion. It's great on film/FX, but it's a weird focal length on DX (42-158) on DX. It's heavy for a consumer lens, and well made, and the macro mode works pretty well if you're experimenting in that area. It collects dust on my shelf, since I've been shooting DX digital for about 7 years, but I could see it making a comeback in my kit if I ever have teh money for a D600.
