I am expanding my manual focus cameras to include a Nikon N2000. I thought this would be a good way to gradually decide if I want to convert from Minolta to Nikon. I am starting with a 50mm f/1.8 lens and want to use an 85 or 100mm lens for some portrait work. I am also hoping that I can use both AF and MF lenses as this is what I understood this particular camera is capable of. Given this, which lens would you recommend next for quick and light portrait work? I do not like or want zooms at this point and can't afford the AF-S lenses. TIA
