OK, I'm going to be picking up a used DSLR in the next week or so. I'm only looking at bodies because the complete kits available used are somewhat limited. Since this won't be coming with a kit lens, what would be a recommended lens? Not necessarily brand vs. brand. But for a SLR newbie looking to learn, doing mostly outdoors and action shots what would be a good range to start with? What should I look for or stay away from?
