Hey folks, I need some help. My d80 and a couple of lenses were stolen about 2 months ago. I'm looking to replace it now and want some advice. I was set on a Nikon d90, but my Father has an old Pentax k1000 and a pentax 50mm 1:2, a tokina 28mm 1:2.8, and a vivitar 70-210 3.8 that are all in pretty good shape despite being 20+years old. So what I'm wondering is this: get a d90 and start from scratch with lenses, or are these lenses worth switching brands and going for a Pentax. And if they are, which Pentax model? Thanks folks, this is my first post.
